I want my local libraries to have priority over the system installed ones, which, as far as I can make out from help(".libPaths"), means they have to come first in that list (it doesn't actually_say_ so, but that seems to be the idea).We have R_LIBS_USER which looks made for specifying where I keep my own libraries. Unfortunately it comes last in .libPaths() [which appears to me to be a bug (1) if that means last in the search order and (2) because install.packages() defaults to the first element in .libPaths() while I think most users would (or rather: should) want to install packages in R_LIBS_USER most of the time]. My options for getting the order I expect seems to be (1) Add to ~/.Rprofile a construct along the lines of: .libPaths(c(Sys.getenv("R_LIBS_USER"), .libPaths())) (2) Add to ~/.Renviron something like: R_LIBS=${R_LIBS_USER}:${R_LIBS} Both of which works but both of which seems very hackish and maybe not robust :-( Is there a better way? Am I missing how R_LIBS* are intended to be used? Allan
I just have R_LIBS=path.to.other.packages in .Renviron. The path to the base-R packages is then automatically appended as the second element of .libPaths().
