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

I get this error when downloading the Rcpp package:

> install.packages("Rcpp", dependencies=TRUE)
Installing package(s) into ‘/home/me/src/Rlibs’ (as ‘lib’ is unspecified)
trying URL 'http://cran.us.r-project.org/src/contrib/Rcpp_0.10.2.tar.gz'
Content type 'application/x-gzip' length 2380089 bytes (2.3 Mb)
...
Warning in dir.create(lockdir, recursive = TRUE) :
  cannot create dir '/home', reason 'Permission denied'
ERROR: failed to create lock directory ‘/home/me/src/Rlibs/00LOCK-Rcpp’
...

As my machine is on a computer cluster, I've tried it on different nodes, and I was careful to delete the temporary files downloaded in /tmp. What is strange is that I have rights to write in /home/me/src/Rlibs/. So my questions are:

  1. why does R want to have writing rights in /home while it only needs writing rights in /home/me/?
  2. how can I fix the error?

Solution

  • 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')
