p.s. Have backup copies of CRAN been made, e.g., annually or with each
new release? Or are there summaries of the tests done with each new
release? I'm looking for something that could be checked to compile a
more accurate and consistent database than what we have now. For me,
this is idle curiosity. However, this could be used to help plan the
expansion of CRAN, providing forecasts with confidence bounds.

For finer level detail, have a look at
https://github.com/hadley/cran-packages. It contains the description
file of every package ever uploaded to CRAN (the cache is a few months
out of date, but you can easily re-run)
Can that be mined to get the date of first commit to CRAN? Dates
in description files are sometimes updated. Example: The "Date" in the
Description file for the version of "fda" now on CRAN is 2013-05, but
fda was on CRAN at least in 2006 and probably earlier. You are listed
as second author on that package based on work you did in by 2006.

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.
