I am using Win 7, 32 bit and R 3.2.0
I want to install few packages via script.
The script should first check if the package is already installed (I
dont want update).
assume the packages are given in a character vector pkg.
pkg <- c("MASS", "A")
Then:
inst <- installed.packages()[,1]
install.packages(setdiff(pkg, inst))

If the package is already there , then it would go
to the next package in my list.
How can I do this ?
