[R-lang] vowel space ellipses (and IPA fonts)

[Roger Levy]

Hi James,

Some more suggestions on your code:

You can suppress printing of the x and y axis ticks respectively by 
passing the parameters xaxt="n" and yaxt="n" in to data.ellipse, and 
cause them to be printed on the top and right by calling axis(3) and 
axis(4) afterward:


if (dots) {
   data.ellipse(F2.F1[Vowel==vn[1]], F1[Vowel==vn[1]], levels=prob,
    col="black", lty=1,
    ylim=c(max(F1),min(F1)),xlim=c(max(F2.F1),min(F2.F1)),
    xlab = "F2-F1 (Hz)", ylab = "F1 (Hz)",xaxt="n",yaxt="n")
axis(3)
axis(4)


It's definitely worth the time investment to read the documentation to 
par {graphics} from beginning to end! There are a lot of neat things in 
there.

The bad news is that I'm not sure exactly how to get the axis labels 
(the words, not the ticks) to print on the right and top. You might try 
playing with the mgp parameter.  If you figure out how to do it, 
definitely let us know!

The R language definition explains why you can't put an "else" on a new 
line in the top level of a script, as Stefan pointed out:

Hope this helps!
