Hi, I'm looking for a way to make executable R-scripts -- which are bound to a certain package -- available to the operating system's search path. The executable R-scripts I put in the package's 'exec' directory. Different solutions have come to my mind: o 'configure'-script copies the files to /usr/local/bin o make a 'require'-shell function which adds '/usr/local/lib/R/site-library/<pkg>/exec' dynamically to $PATH o generate a debian-package which contains separately the executables. Thank you for any suggestions or pointers, Michel

For executable R scripts, I suggest you do 'sudo apt-get install littler' and write scripts for #!/usr/bin/r -- and see the different examples included in the package. My personal convention is to just end thos in a lowercase .r and to 'chmod 755' them, I have a few in ~/bin and /usr/local/bin/. The R packaging system makes it hard to distribute this via packaging as everything is effectively /outside/ the system patch. We work around this using r as well Rscript with things like "Rscript -e 'Rcpp:::LdFlags()'" which we need to call from other packages. Other packages have the same problem (when trying to ship executables based on their code), and there is no solution I can see. For a more general discussion, r-devel may be better anyway.

Just have a Depends: on littler (and whichever R packages you need) and ship scripts in /usr/bin with #!/usr/bin/r as shebang. Dirk -- "Outside of a dog, a book is a man's best friend.
