R Dataset / Package Ecdat / CRANpackages
On this Picostat.com statistics page, you will find information about the CRANpackages data set which pertains to Growth of CRAN . The CRANpackages data set is found in the Ecdat R package. Try to load the CRANpackages data set in R by issuing the following command at the console data("CRANpackages"). This may load the data into a variable called CRANpackages. If R says the CRANpackages data set is not found, you can try installing the package by issuing this command install.packages("Ecdat") and then attempt to reload the data with library("Ecdat") followed by data("CRANpackages"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing CRANpackages at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the CRANpackages R data set. The size of this file is about 1,060 bytes.
Growth of CRAN
Data casually collected on the number of packages on the Comprehensive R Archive Network (CRAN) at different dates.
NOTE: This could change in the future. See Details below.
This seems to provide the most widely available source for data on the growth of CRAN, manually recorded by John Fox and Spencer Graves. For a discussion of these and related data, see Fox (2009).
For more detail, see the

1. It might be nice to have a more complete dataset or datasets
showing CRAN growth. This might include code fitting multiple
models and predicting future growth with error bounds computed
using Bayesian Model Averaging. These model fits might make an
interesting addition to the examples in this help file. With a
little more effort, it might make an interesting note for
R Journal. Functions written to fit those models might
be added to the
