My office supports several local R packages that are central to our workflow. These are all legacy packages, originally developed 5 to 6 years ago. Each time R and R-Studio are updated, we lose the ability to load and use these packages. We receive messages like this:
> install.packages('J:/Estimates/Admin/OLDAppDevelopment/codemogAPI') Installing package into ‘C:/Users/abickford/Documents/R/win-library/4.1’ (as ‘lib’ is unspecified) Warning in install.packages : package ‘J:/Estimates/Admin/OLDAppDevelopment/codemogAPI’ is not available for this version of R A version of this package for your version of R might be available elsewhere, see the ideas at https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages
Is there a workaround for this problem?
And, why is R not backward compatible? The code in these libraries has not changed, why do I lose the functionality when I update R and R-Studio?
