This has gone unnoticed for quite a while:
some Wikistats charts generated with R are no longer updated.
Library probably got missing after server update.
#install.packages(c("Cairo"), repos="http://cran.r-project.org" )
library(Cairo)
Error in library(Cairo) : there is no package called 'Cairo'
Execution halted
Hm, not sure! It totally just worked for me, and all the libcairo2 stuff is installed properly via puppet.

installing to /home/otto/R/x86_64-pc-linux-gnu-library/3.2/Cairo/libs
** R
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (Cairo)Ah, there is a commented line in my R input file, which I overlooked (and apparently is needed just once)
#install.packages(c("Cairo")
After removing the hash I get: error
'lib = "/usr/local/lib/R/site-library"' is not writable'
but after copying your above example faithfully I get option to install at local folder and problem is gone
Thanks!
