Repo is a data-centered data flow manager. It allows to store R data files in a central local repository, together with tags, annotations, provenance and dependence information. Any saved object can then be easily located and loaded through the repo interface.
A paper about Repo has been published in BMC Bioinformatics.
Latest news are found in the NEWS.md file of the “Untested” branch.
Repo is developed by Francesco Napolitano [[alt text][1.2]]
Repository creation in the default folder:
library(repo) rp <- repo_open()
Putting some stuff (it is saved on permanent storage). In this case, just values and names are specified:
rp$put(Inf, "God") rp$put(0, "user")
Putting specifying dependencies:
rp$put(pi, "The Pi costant", depends="God") rp$put(1:10, "r", depends="user")
Getting stuff from the repository on the fly:
diam <- 2 * rp$get("r") circum <- 2 * rp$get("The Pi costant") * rp$get("r") area <- rp$get("The Pi costant") * rp$get("r") ^ 2
Putting with verbose descriptions:
rp$put(diam, "diameters", "These are the diameters", depends = "r") rp$put(circum, "circumferences", "These are the circumferences", depends = c("The Pi costant", "r")) rp$put(area, "areas", "This are the areas", depends = c("The Pi costant", "r"))
print(rp) #> ID Dims Size #> God 1 42 B #> user 1 40 B #> The Pi costant 1 45 B #> r 10 60 B #> diameters 10 65 B #> circumferences 10 94 B #> areas 10 93 B

Master: stable major releases, usually in sync with lastest CRAN version.
Dev: fairly stable minor releases.
Untested: unstable, in progress versions. Latest news appear in the “NEWS.md” file of this branch.
Besides inline help, two documents are available as introductory material:
Repo is on CRAN and can be installed from within R as follows:
However, CRAN versions are not updated very often. Latest stable release can be downloaded from Github at https://github.com/franapoli/repo. Repo can then be installed from the downloaded sources as follows:
> install.packages("path-to-downloaded-source", repos=NULL)
devtools users can download and install at once the latest development version from github as follows:
> install_github("franapoli/repo", ref="dev")
