R devel - Oct 2004 - wide spacing in plotmath() (PR#7324)

Using plotmath produces text whose spacing is very wide. I used the provided
example
x <- seq(-4, 4, len = 101)
y <- cbind(sin(x), cos(x))
matplot(x, y, type = "l", xaxt = "n",
        main = expression(paste(plain(sin) * phi, "  and  ",
                                plain(cos) * phi)),
        ylab = expression("sin" * phi, "cos" * phi), # only
1st is taken
        xlab = expression(paste("Phase Angle ", phi)),
        col.main = "blue")
axis(1, at = c(-pi, -pi/2, 0, pi/2, pi),
     lab = expression(-pi, -pi/2, 0, pi/2, pi))

which produces
      s  i  n   phi   a  n  d              c  o  s    phi
at the top of the graph in the quartz device, the remainder is similarly oddly
spaced. The odd spacing also occurs in demo(plotmath).

I tried the same with R2.0.0 under Windows 2000 where the graphical output was
OK.

This bug has been fixed. It is not a bug specific to the R internals 
but to the R.app version of the quartz device (R.app, i.e. the GUI, 
embeds the R.framework, i.e. R 2.0.0 in your case).

You should look at http://www.economia.unimi.it/R to get the latest 
build of R.app or to get instructions on how to build (just) R.app from 
the latest sources.
