[R] how to save the R script itself into a rData file?

[jim holtman]

Create a function that you can pass the name of the R script to run
and the fileName you want applied to the output files.  First copy the
R script to a file with the 'fileName.R' that as passed in, then
'source' the file to execute it.  Change your script to also use the
'fileName' to create the RData file.  That will create two files
(source and data) that should allow you to recreate your data.
