[R-SIG-Mac] Cairo: Fontconfig error: Cannot load default config file

[Jeroen Ooms]

Running on R 3.1 on my Mavericks laptop:

options(bitmapType = "cairo");
svg("cars.svg", width=11.69, height=8.27)
plot(cars)
dev.off()

Gives a message: Fontconfig error: Cannot load default config file.
The text in the svg seems heavily pixelated. The same happens when
using png().

IIRC, this did not happen on R 3.0, although I am now starting to
doubt this. Is there anything on my machine that I try to
update/reinstall to fix this?

Can you try setting FC_DEBUG environment variable to see what fonts.conf
file it is loading, what fonts it tries to read, etc? The fontconfig
library will print useful output to stderr when the right env bars are set.

Thanks, this was an issue in the fontconfig used by 3.1.0, now fixed. You will need to upgrade R and possibly packages that use fontconfig.

Cheers,

Dear Simon,

I saw your post on this thread. I'm experiencing exactly the same issue right now and don't know how it is "now fixed". Could you please enlighten me on that?

Thanks much,
Yue

Fixed! Thanks a lot!

I am also experiencing a performance regression for svg and png after
upgrading to R 3.1 on Linux. Could that be related to this problem, or
was this problem specific to OSX?

That was specific to the fontconfig binary linked into R for the binary distribution and the config files shipped with it - it had nothing to do with R itself and thus shouldn't really be relevant to other platforms.
