Hi, We have recently installed R 2.0.1 on Solaris 9 (sparc) and downloaded the latest set of BioConductor packages. BioConductor is used by several people here on our Solaris machine and we are finding during testing of the system after installation that there are warning messages appearing when trying to use certain libraries due to insufficient privileges. I had read that it is possible to point to a personal library directory by setting the environment variable R_LIBS. Even when I do this, when loading a library it still appears to be trying to write to the system R/2.0.1/lib/R/library/liblisting.Rda. For example: > .libPaths() [1] "/home/cbrg/validate/myRlibs" "/package/R/2.0.1/lib/R/library" > library(affy) Loading required package: Biobase Loading required package: tools Welcome to Bioconductor Vignettes contain introductory material. To view, simply type: openVignette() For details on reading vignettes, see the openVignette help page. Loading required package: reposTools Warning messages: 1: Incorrect permissions to edit package database, /package/R/2.0.1/lib/R/library/liblisting.Rda in: save.locLib(locLibList, curLib) 2: Incorrect permissions to edit package database, /package/R/2.0.1/lib/R/library/liblisting.Rda in: save.locLib(locLibList, curLib) > In this case, this doesn't stop the user using the affy package (in fact this seems to be an issue with reposTools) but the warnings are a little disconcerting. Apologies if this is more of an R question but I wondered if anyone else had encountered this and if there is a solution to fix it?
