Dear all,Ghostscript (version 9.05) cannot open pdfs produced with R (version 3.0.2) that contain very small points in plots. Other pdf readers (evince, AcrobatReader) are able to open the file. If setting cex=0, the pdf is readable again: # does open with gs pdf("cex_small.pdf") plot(1,1,cex=10^-3) dev.off() # does not open with gs pdf("cex_verysmall.pdf") plot(1,1,cex=10^-4) dev.off() # does open with gs pdf("cex_zero.pdf") plot(1,1,cex=0) dev.off() For sure, I can check the value assigned to cex before plotting. However, this is rather inconvenient. I need to convert the graphs using convert to other file formats, hence simply using another pdf readers is not an option either. Any suggestions?
From your description, it sounds like a Ghostscript bug, so you might want to report it to them. But a simple workaround is to just round your cex values, e.g. use round(cex, 2) and 0.001 will become 0.
