3.87 GB and 3786 packages. Thats what you need to install the whole of R as on CRAN
( Note- Many IT administrators /Compliance Policies in enterprises forbid installing from the Internet in work offices.
Which is where the analytics,$$, and people are)
As downloaded from the CRAN Mirror at UCLA.
Takes 3 hours to download at 1 mbps (I was on an Amazon Ec2 instance)
Next question- who is the man responsible in the R project for deleting old /depreciated/redundant packages if the authors dont do it.
