Added a NEWS.md file to track changes to the
package.
Added argument pos_def to function
rand_cor_mat to make bending of a non-positive-definite
correlation matrix to a positive-definite matrix optional.
Added example data frame df_error_bivar with plot
errors for two traits across three locations generated using
field_trial_error.
Added example data frame df_gv_unstr with simulated
genetic values for two traits across three environments generated using
unstr_asr_input and unstr_asr_output.
Added functionality to simulate extraneous variation to
field_trial_error.
Added internal functions spline_interp and
fill_matrix to interpolate and extrapolate missing values
if some NAs remain after bivariate interpolation.
Added make_phenotypes to create phenotypes through
combination of genetic values and plot errors.
Added qq_plot to compare the theoretical quantiles
of a normal distribution with the sample quantiles of the distribution
of a user-defined effect.
Added sample_variogram to create a variogram of a
user-defined effect.
Added theoretical_variogram to create a theoretical
variogram.
Added vignette compound_symmetry_GxE_demo to
demonstrate the simulation of genetic values using a compound symmetry
GxE model.
Added vignette spatial_error_demo to demonstrate the
simulation of plot errors and phenotypes for a multi-environment plant
breeding trial.
Added vignette unstructured_GxE_demo to demonstrate
the simulation of genetic values using an unstructured GxE
model.
Removed argument env from function
plot_effects.
Replaced package fields for graphics in
plot_effects by ggplot2.
Set the complexity argument of
field_trial_error by default to the maximum number of
columns and rows in each environment.
Updated Description in DESCRIPTION.
