Dear R-Helpers,
I have a problem with displaying the greek "beta" symbol in PDF files
using Cairo library - it displays as an empty box. The same also happens
for a dash symbol in subscript. Both symbols are displayed correctly if
the plot is produced on screen (outside of CairoPDF).
The syntax that I use for it in plot command is:
'xlab=expression(paste("A",beta,)[1-42])'.
When I try to select a different font family using 'family' option in
the CairoPDF command - it has no effect. I tried 'CairoFonts', but it
displays an error:
'Warning message:
In CairoFonts() :
the R Cairo package was not installed with fontconfig. Please
consider installing the cairo graphics engine (www.cairographics.org)
with freetype and fontconfig support'
I have the most recent GTK+ installed. I don't know where to look for
solution. Anyone able to help?
Here is my session info:
