I noticed this running a few graphics demos the other day. In particular the plotmath and the persp graphics demos, certain fonts don't seem to render on the demos.
The plotmath demo displays certain math equations on a quartz window that don't render properly, and the persp demo displays a 3D model of a mountain with labels on the graph rendered in a certain font. (None of the data labels render at all.) This problem appeared recently, (like last week), and has not happened before. I'm fairly new to using the R gui and R in general, so I don't really know where to check if I have the proper true type fonts available on my computer or if it is a problem within R itself. This doesn't appear to be a problem with the functioning of R itself, just an inability for it to render certain fonts on graphical displays. I just want to fix it now before I use it in a major project that requires the rendering of fonts onto the screen for presentations etc... ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
