I am new at R.
I am trying to see if R can work for me.
I need to do database like lookup (select * from table where
name=='toto') and work with matrix (transpose, add columns, remove
rows, etc).
It seems that the data.table package can help.

I installed R and ...

> install.packages("data.table")
Warning in install.packages("data.table") :
  argument 'lib' is missing: using '/usr/local/lib/R/site-library'
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘data.table’ is not available

> install.packages()
doesn't show the package.

where can I find it?
