How do you change library location in R? [duplicate]
You can edit Rprofile in the base library (in 'C:/Program Files/R.Files/library/base/R' by default) to include code to be run on startup. Append
######## User code ########.libPaths('C:/my/dir')to Rprofile using any text editor (like Notepad) to cause R to add 'C:/my/dir' to the list of libraries it knows about.
(Notepad can't save to Program Files, so save your edited Rprofile somewhere else and then copy it in using Windows Explorer.)
This post is just to mention an additional option. In case you need to set custom R libs in your Linux shell script you may easily do so by
export R_LIBS="~/R/lib"See R admin guide on complete list of options.
I've used this successfully inside R script:
library("reshape2",lib.loc="/path/to/R-packages/")useful if for whatever reason libraries are in more than one place.
