To the list readers: I posted a comment to the identical SO question that changing the font with CairoFonts before the CairoPDF call might be more effective. (I used a font name of "TimesNewRoman" rather than "Times New Roman" but testing with CairoFontMatch(fontpattern="Times New Roman",sort=FALSE,verbose=TRUE) ... proved that the spaces were not causing problems. I happen to have a copy of Times New Roman since I have purchased MS Office, but I do not know if everyone would have that font installed. ) This succeeded CairoFonts( regular="Roman-12:normal", italic="Roman-12:italic" ) # The default family is Helvetica on my machine running OSX 10.7.5 -- David Winsemius Alameda, CA, USA ______________________________________________ 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.
