Thanks very much for the packaging. I think I found the answer about missing glyphs. I followed the debugging advice that BDR put in that bugzilla entry mentioned in my last note. The culprit was a copy of the microsoft symbol.ttf was in my user account font folder. That used to be a good thing, but apparently no more. It causes 1) R to not be able to display lceil and other large braces and 2) Evince cannot display some sizes of "mu" and "<=". As soon as that file is removed, then everything seems to display just fine.
Oh, one more thing. I can confirm the claim in that bug report that R itself is writing proper PDF output, the problem is only in the display on screen in a given system. Embedding the fonts always solves this trouble, however, so if one is unable to remove a troubled font or fiddle around it, there is still a straightforward fix. pj On Sun, May 12, 2013 at 12:08 PM, Johannes Ranke <[email protected]>wrote: > Hi, > > The R 3 packages for wheezy are currently being built for i386 and amd64. > If > all goes well, they will be available within the next two days. > > As for R on Debian wheezy, I just checked demo(plotmath) on the default R > 2.15.1 on wheezy, and it produced all the nice plotting symbols I would > expect > in good quality.
