This function is part programming exercise and part solution to R upgrades.
Only install.packages() pkgs param is supported. For devtools::install_*
functions, only the first parameter, usually repo, is supported. If you need
something more advanced, there are plenty of similar functions already written.
reinstall_packages(pkgs = my_packages)
devtools::install_* functions are specified as a character
vector of 2 strings. The first string is the suffix to complete the install
funciton name. The second string is the path to the package. If this param
is not specified, the set is defaulted to dgutils::my_packages.TRUE
Each R release has its own library, /Library/Frameworks/R.framework/Versions/x.x/Resources/library.
To avoid redoing the package installs into the new R library, I added this entry to .Renviron:
R_LIBS_USER=~/Library/R/3.x/library/and this function to make managing multiple computers eaiser.
It's possible that my_packages will become an option.
