This really seems like an R question to me rather than a cairo one,
but as far as cairo goes, you may be able to have some influence over
font selections by tweaking your personal fontconfig file


Depending on how R selects fonts this might actually work, but I still
think you'll have better control if you can tell R about your choices

You mention that you're using a custom compiled cairo rather than the
system one and that you're pointing R to it using various environment
variables.  Are you doing this because R doesn't work with the system
cairo at all?  It's not clear to me what relevance that has to your
problem with fonts.
