==========

Each R package installation must be tested during the installation.

Solution:
install.packages does not throw an exception when package is not found (wrong name, or too old version)
but library(foobar) throw an exception.

Solution: add the following lines to the R package installation script

tryCatch(library(FactoMineR), error=function(e) q(status=1))
tryCatch(library(Rserve), error=function(e) q(status=1))
tryCatch(library(textometry), error=function(e) q(status=1))
