Multiple font families in ggsave

[Ravina, Mark]

I need to use multiple font families in a single graph and save the output as a pdf. 

Kohske’s code (adapted below) is great for a single Japanese font family, but the Japanese font won’t map the Unicode character  “ō” and generates the warning 

In grid.Call.graphics(L_text, as.graphicsAnnot(x$label), x$x, x$y,  :

  failed in text conversion to encoding 'EUC-JP’

How do I keep the default font of ggplot (I’m quite pleased with that output) but add a Japanese font family? CairoPDF seems to have parallel problems.

d <- data.frame(x=1:2, y=1:2, t=c("あ","ō"))

a <- ggplot(d, aes(x, y, label=t)) + geom_text() + ggtitle("う")

ggsave("out.pdf", a, family="Japan1GothicBBB”)

I can't speak to your specific issue, but Winston Chang's extrafont package seems like a good place to start. Here is a blog post he did that discusses it: http://blog.revolutionanalytics.com/2012/09/how-to-use-your-favorite-fonts-in-r-charts.html
