When I try to install devtools in Rstudio 3.2.3 (Windows 10) using the command install.packages("devtools"), I get the following message:
warning in install.packages :
'lib = "c:/Program Files/R/R-3.2.3//library"' is not writable
I'm a newby and I've been hunting for solutions but so far am coming up empty. I would appreciate any advice that might get me through this step. Thanks.
