Install a list of packages
common_packages <- c('batch','data.table','plyr','sqldf')
## adjust as necessary, see help('download.packages')
repos <- "http://cran.rstudio.com"

lib.loc <- "/usr/local/lib/R/site-library/"
## install packages
sapply(common_packages, function (pkg) install.packages(pkg, lib.loc, repos))
