[R] Growth of CRAN?

[Spencer Graves]

       What data exist on the growth of CRAN?


       John Fox published some data on it in 2009 ("Aspects of the 
Social Organization and Trajectory of the R Project", R Journal, 
http://journal.r-project.org/archive/2009-2/RJournal_2009-2_Fox.pdf). 
Below please find those numbers plus some additions of mine since. If 
anyone else has other numbers (or more accurate numbers), I'd like to know.


       I plan to add a "CRANpackages" data set to the "Ecdat" package 
with a title, "Growth of CRAN" unless someone else provides better 
numbers or title.  [If it already exists on CRAN, I'd like to know. I 
doubt if it does, because I couldn't find it with findFn{sos} for 
'number of CRAN packages' and 'growth of CRAN'.]


       Thanks,
       Spencer

* NOTE:  These numbers may differ slightly from other sources. Numbers 
through 2009 were read from a plot in Fox's paper.  Numbers since were 
read at an arbitrary time during the day, Pacific time, from a mirror in 
the United States and could differ from those recorded by someone else 
using a different mirror having the same date in local time  someplace 
else.
