Use installed.packages()
to check DESCRIPTION file for each package
folder, more accurate than checking name only. R help cautioned it be slow if
thouands of packages available, but checking 300 ~ 400 packages didn't have
significant performance difference. It's recommended to always use this unless
it's too slow for you.
