R_PDFVIEWER not set in most recent R built in Karmic

[Dirk Eddelbuettel]

Binary package hint: r-base

This bug was originally reported on the r-sig-debian list (for Debian / Ubuntu user of R).

R_PDFVIEWER ends up as being undefined in /etc/R/Revnviron meaning that commands to launch pdf documents fail (unless the user set a pdf viewer option herself).

The problem was that the test for xdg-open as a pdf viewer had dropped upstream (and is back in R 2.10.0 beta). I fixed this in Debian release 2.9.2-4, and have just place a new 'sync' from Debian in the revor PPA on launchpad as 2.9.2-3ubuntu1~ppa1.

Other than the bug fix, this release also has a new 'greeting text' in /etc/R/Rprofile.site -- with a much shorter two-line text about REvolution R packages (in case none are installed).

So if this bui;d could get moved into Karmic it would be good.
