[R] [R-SIG-Mac] Plotting Chinese characters

[Simon Urbanek]

Alberto,

you simply need a font that has those characters. For example on 10.6 this works:

plot.new(); plot.window(0:1,0:1); text(0.5,0.5,"精市",cex=10,family="Hei")

You may want to check your system for fonts that you can use (those that have chinese characters when you click on them in Font Book). There are a lot of fonts that work like STSong, STFangsong, LiSong Pro, AppleMyungjo, GungSeo etc.

Cheers,
Simon
