R help - Sep 2000 - phantom(0) doesn't do what I expect it to [plotmath]

Hi,

I'm trying to make a legend with a justified list of numbers, so I
thought I would use phantom(0) to align the 3-digit numbers properly
with the 4-digit ones:

    legend(x, y, xjust=1, yjust=1, lty=c(1,2,3,4,5), adj=c(0,0.5),
           legend=expression(phantom(0)*300*plain(K),
                             phantom(0)*550*plain(K),
                             phantom(0)*830*plain(K),
                                       1440*plain(K),
                                       2500*plain(K)))

Unfortunately, phantom(0) doesn't seem to be adding any space, whether
I use the X11 or the postscript device.

Am I being obtuse? Should I file a PR?

Suggestions for alternative solutions also appreciated (short of
measuring all the string widths and building it up by hand ;-)

cheers,

Malcolm

No, yes. This looks like a bug, and even stuff advertised on the help
page using phantom(0) doesn't seem to work.

BTW : It's helpful if examples to reproduce a bug are directly
executable. I.e. plot(1);legend(1,1,...etc...)
