I am having trouble showing the Greek symbol "beta" correctly in the y-axis label of bitmap plots.

Specifically, on my system the top of the "beta" symbol is cut off using the following example:

file.jpg <- paste(tempfile(), ".jpg", sep = "")

jpeg(file.jpg, h = 3, w = 3, units = "in", res = 300, type = "Xlib") boxplot(rnorm(10), ylab = expression(beta)) dev.off()

I have the same problem with tiff() and png(). I don't have cairo capabilities on this system.

On another system with cairo, if I use 'type = "cairo"' the jpeg is correct. If I use 'type = "Xlib", I get this error:

Error in title(ylab = expression(beta)) :   X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 5 at size 12 could not be loaded

My system information is below.
