   As a linux-only user for more than two decades I really appreciate the
value of running scripts from the command line. For a current project, after
extracting 29 years of data from PDF forms I ran them through a bash shell
script (passing the name of the source file as $1) that calls two sed and
six awk scripts. The output is ready to be read into R.

   This is what I need to work out now for Rscript: how to set positional or
named parameters on the command line with the source file name and the R
data.frame name.

   Thanks for your comments.

Best regards,
