Thanks Professor Ripley. I'd looked at the R Windows FAQ but not carefully enough.Using Renviron.site does seem much more elegant than Rprofile.site. I've now included a line in Renviron.site R_LIBS_SITE=//Server02/stats/R/library I also note your use of site and personal libraries specific to "first decimal" versions of R. Would you recommend others to follow this practice?
