Please ignore my question. The directory argument to .libPaths() was incorrect. Is there a way to trigger an error message? Thanks, Mike ---------- Forwarded message ---------- From: hugo hovawart Date: Mon, Jun 13, 2011 at 8:51 AM Subject: .libPaths() To: ess I'm using ESS 5.10 in Emacs 23.1.1 on Ubuntu Meerkat with R version 2.11.1. The R process in ESS is not using the same .libPaths() as R started in a terminal window. I read some posts from years ago and have tried the following: 1. Included a .Renviron file with: R_LIBS=/home/mike/dev/R/libs/2.11.1 (my local package library) 2. Tried running .libPaths() in ESS. > .libPaths() [1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library" [3] "/usr/lib/R/library" "/usr/lib64/R/library" > .libPaths(c("/home/mike/dev/R/libs/2.11.1",.libPaths())) > .libPaths() [1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library" [3] "/usr/lib/R/library" "/usr/lib64/R/library" > I don't know why .libPaths() is the same before/after adding my local lib dir. When I start R from a terminal the lib path is set correctly. Thanks [[alternative HTML version deleted]]
