[R] Changing expression font

[Prof Brian Ripley]

You have not told us the device you are using, nor your version of R.

The way to select 'Times New Roman' is via the family, which will work if 
it is supported on the device and your R is current (2.3.0, preferably 
patched).

font=6 is only supported on a few devices, and not on X11 on Linux.
There you can choose Times via options("X11Fonts").

For example,

pdf(family="Times")
plot(x=my.df[,1], y=my.df[,2],
      xlab=expression(paste("Independent(",mu,"g/L)")),
      ylab=expression(paste("Dependent (",mu,"g/L)")))

works (on FC3 and Windows).
