As of this release, the broom team will be following a set of guidelines that clarify the scope of further development on the package. Given the package’s wide use and long history, these guidelines prioritize backward compatibility over internal consistency and completeness. You can read those guidelines here!
We’ve also made notable changes to error handling in this release:
tidy() methods will now warn when supplied an
exponentiate argument if it will be ignored.augment() methods will now warn when supplied a
newdata argument if it will be ignored.lm and glm is now displayed only once per
session, per unique dispatch. That is, if a class_a object
is tidied using a (g)lm method, broom will not warn when
tidying class_a objects for the rest of the session, but if
a class_b object is tidied using a (g)lm
method in the same session, broom will warn again (#1101).Other fixes and improvements:

car::lht() output in tidy.anova() (#1106 by
@grantmcdermott).glance.anova method (which previously
dispatched to theglance.data.frame() tidier, #1106 by

that subclassed lm and relied on tidy.lm(), or
similarly for tidy.glm(). Tidiers for these objects were
supported unintentionally, and we worried that tidiers for these objects
would silently report inaccurate results.
In hindsight, this change was unnecessarily abrupt. We’ve decided to
roll back this change, instead providing the following warning before
allowing such objects to fall back to the
lm/glm tidier methods:
Tidiers for objects of class {subclass} are not maintained by the broom team, and are only supported through the {dispatched_method} tidier method. Please be cautious in interpreting and reporting broom output.”

returned if exponentiate = FALSE.We followed through with the planned deprecation of character vector tidiers in this release. Other vector tidiers that were soft-deprecated in 0.7.0 will be fully deprecated in a later release.
broom 0.7.0 is a major release with a large number of
new tidiers, soft-deprecations, and planned hard-deprecations of
functions and arguments.
We have changed how we report degrees of freedom for
lm objects (#212, #273). This is especially important for
instructors in statistics courses. Previously the df column
in glance.lm() reported the rank of the design matrix. Now
it reports degrees of freedom of the numerator for the overall
F-statistic. This is equal to the rank of the model matrix minus one
(unless you omit an intercept column), so the new df should
be the old df minus one.
We are moving away from supporting summary.*()
objects. In particular, we have removed tidy.summary.lm()
as part of a major overhaul of internals. Instead of calling
tidy() on summary-like objects, please call
tidy() directly on model objects moving forward.
We have removed all support for the quick argument
in tidy() methods. This is to simplify internals and is for
maintainability purposes. We anticipate this will not influence many
users as few people seemed to use it. If this majorly cramps your style,
let us know, as we are considering a new verb to return only model
parameters. In the meantime, stats::coef() together with
tibble::enframe() provides most of the functionality of
tidy(..., quick = TRUE).
All conf.int arguments now default to
FALSE, and all conf.level arguments now
default to 0.95. This should primarily affect
tidy.survreg(), which previously always returned confidence
intervals, although there are some others.
Tidiers for emmeans-objects use the arguments
conf.int and conf.level instead of relying on
the argument names native to the emmeans::summary()-methods
(i.e., infer and level). Similarly,
multcomp-tidiers now include a call to
summary() as previous behavior was akin to setting the now
removed argument quick = TRUE. Both families of tidiers now
use the adj.p.value column name when appropriate. Finally,
emmeans-, multcomp-, and
TukeyHSD-tidiers now consistently use the column names
contrast and null.value instead of
comparison, level1 and level2, or
lhs and rhs (see #692).
This release of broom soft-deprecates the following
functions and tidier methods:
bootstrap()confint_tidy()fix_data_frame()finish_glance()augment.glmRob()tidy.table() and tidy.ftable() have been
deprecated in favor of tibble::as_tibble()tidy.summaryDefault() and
glance.summaryDefault() have been deprecated in favor of
skimr::skim()We have also gone forward with our planned mixed model deprecations,
and have removed the following methods, which now live in
broom.mixed:
tidy.brmsfit()tidy.merMod(), glance.merMod(),
augment.merMod()tidy.lme(), glance.lme(),
augment.lme()tidy.stanreg(), glance.stanreg()tidyMCMC(), tidy.rjags(),
tidy.stanfit()augment.factanal() now returns a tibble with columns
names .fs1, .fs2, …, instead of
factor1, factor2, … (#650)
We have renamed the output of augment.htest(). In
particular, we have renamed the .residuals column to
.resid and the .stdres to
.std.resid for consistency. These changes will only affect
chi-squared tests.
tidy.ridgelm() now always return a GCV
column and never returns an xm column. (#533 by @jmuhlenkamp)
tidy.dist() no longer supports the
upper argument.
augment() methodsThe internals of augment.*() methods have largely been
overhauled.
If you pass a dataset to augment() via the
data or newdata arguments, you are now
guaranteed that the augmented dataset will have exactly the same number
of rows as the original dataset. This differs from previous behavior
primarily when there are missing values. Previously
augment() would drop rows containing NA. This
should no longer be the case.
augment.*() methods no longer accept an
na.action argument.
In previous versions, several augment.*() methods
inherited the augment.lm() method, but required additions
to the augment.lm() method itself. We have shifted away
from this approach in favor of re-implementing many
augment.*() methods as standalone methods making use of
internal helper functions. As a result, augment.lm() and
some related methods have deprecated (previously unused)
arguments.
augment() tries to give an informative error when
data isn’t the original training data.
The .resid column in the output of
augment().* methods is now consistently defined as
y - y_hat

recover the old behavior.
Previously, F-statistics for weak instruments were returned
through glance.ivreg(). F-statistics are now returned
through tidy.ivreg(instruments = TRUE). Default is
tidy.ivreg(instruments = FALSE).
glance.ivreg() still returns Wu-Hausman and Sargan test
statistics.

column, which contains the number of data points used to fit the model!
(#597 by @vincentarelbundock)
tidy() no longer checks for a log or logit link when
exponentiate = TRUE, and we have refactored to remove
extraneous exponentiate arguments. If you set
exponentiate = TRUE, we assume you know what you are doing
and that you want exponentiated coefficients (and confidence intervals
if conf.int = TRUE) regardless of link function.
We now use rlang::arg_match() when possible instead
of arg.match() to give more informative errors on argument
mismatches.
The package’s site has moved from https://broom.tidyverse.org/ to https://broom.tidymodels.org/.
Revised several vignettes and moved them to the tidymodels.org website. The existing vignettes will now simply link to the revised versions.
Many improvements to consistency and clarity of documentation.
Various warnings resulting from changes to the tidyr API in v1.0.0 have been fixed. (#870)
Removed dependencies on reshape2 and superseded functions in dplyr.
All documentation now links to help files rather than topics.
Moved core tests to the modeltests package.
Generally, after this release, the broom dev team will first ask that attempts to add tidier methods supporting a model object are first directed to the model-owning package. An article describing best practices in doing so can be found on the {tidymodels} website at https://www.tidymodels.org/learn/develop/broom/, and we will continue adding additional resources to that article as we develop them. In the case that the maintainer is uninterested in taking on the tidier methods, please note this in your issue or PR.
Added a new vignette discussing how to implement new tidier methods in non-broom packages.
tibble 3.0.0 release.
Removed xergm dependency.Fixes failing CRAN checks
Changes to accommodate ergm 3.10 release.
tidy.ergm() no longer has a quick argument.
The old default of quick = FALSE is now the only
option.
tidy(), glance() and
augment() are now re-exported from the generics package.Tidiers now return tibble::tibble()s. This release also
includes several new tidiers, new vignettes and a large number of bug
fixes. We’ve also begun to more rigorously define tidier specifications:
we’ve laid part of the groundwork for stricter and more consistent
tidying, but the new tidier specifications are not yet complete. These
will appear in the next release.
Additionally, users should note that we are in the process of
migrating tidying methods for mixed models and Bayesian models to
broom.mixed. broom.mixed is not on CRAN yet,
but all mixed model and Bayesian tidiers will be deprecated once
broom.mixed is on CRAN. No further development of mixed
model tidiers will take place in broom.
Almost all tidiers should now return tibbles rather than
data.frames. Deprecated tidying methods, Bayesian and mixed
model tidiers still return data.frames.
Users are mostly to experience issues when using
augment in situations where tibbles are stricter than data
frames. For example, specifying model covariates as a matrix object will
now error:
library(broom)
library(quantreg)
fit <- rq(stack.loss ~ stack.x, tau = .5)
broom::augment(fit)
#> Error: Column `stack.x` must be a 1d atomic vector or a listThis is because the default data argument
data = model.frame(fit) cannot be coerced to
tibble.
Another consequence of this is that augment.survreg and
augment.coxph from the survival package now
require that the user explicitly passes data to either the
data or newdata arguments.
These restrictions will be relaxed in an upcoming release of
broom pending support for matrix-columns in tibbles.
Developers are likely to experience issues:
subsetting tibbles with [, which returns a tibble
rather than a vector.
setting rownames on tibbles, which is deprecated.
using matrix and vector tidiers, now deprecated.
handling the additional tibble classes tbl_df and
tbl beyond the data.frame class
linking to defunct documentation files – broom recently moved all
tidiers to a roxygen2 template based documentation
system.
This version of broom includes several new
vignettes:
vignette("available-methods", package = "broom")
contains a table detailing which tidying methods are available
vignette("adding-tidiers", package = "broom") is an
in-progress guide for contributors on how to add new tidiers to
broom
vignette("glossary", package = "broom") contains
tables describing acceptable argument names and column names for the
in-progress new specification.
Several old vignettes have also been updated:
vignette("bootstrapping", package = "broom") now relies
on the rsample package and a
tidyr::nest-purrr::map-tidyr::unnest
workflow. This is now the recommended workflow for working with multiple
models, as opposed to the old
dplyr::rowwise-dplyr::do based workflow.Matrix and vector tidiers have been deprecated in favor of
tibble::as_tibble and tibble::enframe
Dataframe tidiers and rowwise dataframe tidiers have been deprecated
bootstrap() has been deprecated in favor of the rsample
inflate has been removed from
broom
The alpha argument has been removed from
quantreg tidy methods
The separate.levels argument has been removed from
tidy.TukeyHSD. To obtain the effect of
separate.levels = TRUE, users may
tidyr::separate after tidying. This is consistent with the
multcomp tidier behavior.
The fe.error argument was removed from
tidy.felm. When fixed effects are tidier, their standard
errors are now always included.
The diag argument in tidy.dist has been
renamed diagonal

Jonah Gabry)
Fixed issue with survival package 2.40-1 (thanks to #180 from Marcus Walz)
Added AppVeyor, codecov.io, and code of conduct
Changed name of “NA’s” column in summaryDefault output to “na”
Fixed tidy.TukeyHSD to include term
column. Also added separate.levels argument, with option to
separate comparison into level1 and
level2
Fixed tidy.manova to use correct column name for
test (previously, always pillai)
Added kde_tidiers to tidy kernel density
estimates
Added orcutt_tidiers to tidy the results of
cochrane.orcutt orcutt package
Added tidy.dist to tidy the distance matrix output
of dist from the stats package
Added tidy and glance for
lmodel2 objects from the lmodel2 package
Added tidiers for poLCA objects from the poLCA
package
Added tidiers for sparse matrices from the Matrix package
Added tidiers for prcomp objects
Added tidiers for Mclust objects from the Mclust
package
Added tidiers for acf objects
Fixed to be compatible with dplyr 0.5, which is being submitted to CRAN
Added tidiers for geeglm, nlrq, roc, boot, bgterm, kappa, binWidth, binDesign, rcorr, stanfit, rjags, gamlss, and mle2 objects.
Added tidy methods for lists, including u, d, v
lists from svd, and x, y, z lists used by
image and persp
Added quick argument to tidy.lm,
tidy.nls, and tidy.biglm, to create a smaller
and faster version of the output.
Changed rowwise_df_tidiers to allow the original
data to be saved as a list column, then provided as a column name to
augment. This required removing data from the
augment S3 signature. Also added
tests-rowwise.R
Fixed various issues in ANOVA output
Fixed various issues in lme4 output
Fixed issues in tests caused by dev version of ggplot2
Added tidiers for “plm” (panel linear model) objects from the plm package.
Added tidy.coeftest for coeftest objects from the
lmtest package.
Set up tidy.lm to work with “mlm” (multiple linear
model) objects (those with multiple response columns).
Added tidy and glance for “biglm” and
“bigglm” objects from the biglm package.
Fixed bug in tidy.coxph when one-row matrices are
returned
Added tidy.power.htest
Added tidy and glance for
summaryDefault objects
Added tidiers for “lme” (linear mixed effects models) from the nlme package
Added tidy and glance for
multinom objects from the nnet package.
Fixed bug in tidy.pairwise.htest, which now can
handle cases where the grouping variable is numeric.
Added tidy.aovlist method. This added
stringr package to IMPORTS to trim whitespace from the
beginning and end of the term and stratum
columns. This also required adjusting tidy.aov so that it
could handle strata that are missing p-values.
Set up glance.lm to work with aov
objects along with lm objects.
Added tidy and glance for matrix
objects, with tidy.matrix converting a matrix to a data
frame with rownames included, and glance.matrix returning
the same result as glance.data.frame.
Changed DESCRIPTION Authors@R to new format
Fixed small bug in felm where the
.fitted and .resid columns were matrices
rather than vectors.
Added tidiers for rlm (robust linear model) and
gam (generalized additive model) objects, including
adjustments to “lm” tidiers in order to handle them. See
?rlm_tidiers and ?gam_tidiers for
more.
Removed rownames from tidy.cv.glmnet output
The behavior of augment, particularly with regard to
missing data and the na.exclude argument, has through the
use of the augment_columns function been made consistent
across the following models:
lm
glm
nls
merMod (lme4)
survreg (survival)
coxph (survival)
Unit tests in tests/testthat/test-augment.R were added
to ensure consistency across these models.
tidy, augment and glance
methods were added for rowwise_df objects, and are set up
to apply across their rows. This allows for simple patterns such
as:regressions <- mtcars %>% group_by(cyl) %>% do(mod = lm(mpg ~ wt, .)) regressions %>% tidy(mod) regressions %>% augment(mod)
See ?rowwise_df_tidiers for more.
Added tidy and glance methods for
Arima objects, and tidy for
pairwise.htest objects.
Fixes for CRAN: change package description to title case, removed
NOTES, mostly by adding globals.R to declare global
variables.
This is the original version published on CRAN.
Tidiers have been added for S3 objects from the following packages:
lme4
glmnet
survival
zoo
felm
MASS (ridgelm objects)
tidy and glance methods for data.frames
have also been added, and augment.data.frame produces an
error (rather than returning the same data.frame).
stderror has been changed to std.error
(affects many functions) to be consistent with broom’s naming
conventions for columns.
A function bootstrap has been added based on this example,
to perform the common use case of bootstrapping models.
Added “augment” S3 generic and various implementations. “augment” does something different from tidy: it adds columns to the original dataset, including predictions, residuals, or cluster assignments. This was originally described as “fortify” in ggplot2.
Added “glance” S3 generic and various implementations. “glance” produces a one-row data frame summary, which is necessary for tidy outputs with values like R^2 or F-statistics.
Re-wrote intro broom vignette/README to introduce all three methods.
Wrote a new kmeans vignette.
Added tidying methods for multcomp, sp, and map objects (from fortify-multcomp, fortify-sp, and fortify-map from ggplot2).
Because this integrates substantial amounts of ggplot2 code (with permission), added Hadley Wickham as an author in DESCRIPTION.
