Hello, I am developing a package that needs data to persist between sessions of R (For example a sqlite database file, or simple dumps of R data with save/load). What I am using so far is : file.path( Sys.getenv( "HOME"), ".R", "myPackage" ) but I was wondering if I am missing an "official" way to do this, similar to system.file does for installed packages. I am aware of the inst directory but this does not solve the problem in cases where the library is read only.
