...using too long pathnames for bitmap() crash R on WinXP. I've verified that this is the case with R version 2.4.1 Patched (2007-03-25 r40958) and R version 2.5.0 alpha (2007-03-30 r40957). I cannot reproduce it on Linux.

Hi, I don't know if I am the first one to report the problem: in 2.8.0 dev2bitmap gained aa support, but "extra" is null if neither taa nor naa is specified. > dev2bitmap("plot.pdf",type="pdfwrite") Error in paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=", type, : object "extra" not found > dev2bitmap("plot.pdf",type="pdfwrite",taa=4) > I guess a useful default for extra is missing: if (!is.na(taa)) extra <- paste(" -dTextAlphaBits=", ta...

Hi, I've installed several versions of R on a number of Window systems. I get the following error message (which I don't get on linux) > dev2bitmap(file="test.jpeg",type="jpeg") Error in system(paste(gsexe, "-help"), intern = TRUE, invisible = TRUE) : gswin32c.exe not found Any idea how to fix this? It seems common to all windows systems I've tried. Is there a package I can install that will correct this? Best wishes, Harry -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~...

I have two questions - 1. I am trying to create R png graphs via cron. I have this part working using Xvfb (X virtual frame buffer). One problem that I have, though, is that all the fonts on my graphs get messed up. Anybody have any nija R commands to make all fonts look great? Anybody have any idea how to fix this? So far, no luck on Solaris or Linux making the Xvfb fonts look good. I was
