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.
