The initial stage (# get txt-file name and open it ) gives me an error:
Error: could not find function "shell.exec"
Any idea?
BTW, also function shell() for text mining seems to be restricted under Linux.

I'm guessing that you refer to https://github.com/gimoya/theBioBucket-Archives/blob/master/R/txtmining_pdf.R#l16 ...
shell.exec as well as shell() and system() are Win-only, as you can take from the docs!
