I can post the R packages for Wheezy on my website if anybody wants them. Now, back to the "no glyph" problem. Does > demo(plotmath) work for you on Debian 7? Here's a re-producible example that generates bad on-screen output for me. plot(0~0, type = "n") text(.4, expression(group(lceil,x, rceil)), cex=0.5) The glyphs for the left and right braces look like "dominoes". I found a thread from 2010 about a similar problem, but that case blamed the Wine fonts. Now I suspect some other bad symbol font has found its way to the front of my path. https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14355 That thread points out that using the Xlib version of the X11 device SOLVES the problem, but at the price of slightly lower quality of output. If I want to use the default Cairo device, apparently I have to fiddle something. I am experimenting with the debugging and fontconfig adjustments that might be used to avoid the trouble. To the non-full-time-font administrator like me, this is a bit overwhelming because there are so many different types of fonts. pj > -- > Charles Plessy > -- Paul E.
