R install.packages returns "failed to create lock directory"

On NFS file systems it is sometimes not obvious what things you have to close.

The best way to avoid this is to use the --no-lock argument on the command line, i.e.:

R CMD INSTALL --no-lock <pkg>

From within R, you can do this from within your command using:

install.packages("Rcpp", dependencies = TRUE, INSTALL_opts = '--no-lock')

This happens when your last package installation has interrupted abnormally. to fix this you should remove the locked file. For example Execute this command in R console:

unlink("/home/me/src/Rlibs/00LOCK-Rcpp", recursive = TRUE)

Hope this helps!
