[R] Specifying relative position of text in a plot

[Greg Snow]

I tested the main set of examples from cnvrt.coords using the new
grconvert functions and they worked perfectly.  I have already noted in
the help page for cnvrt.coords (for the next version coming out soon)
that people should start using grconvertX and grconvertY when they
become available.

Are there any more of the utilities in TeachingDemos that will be need
to be depricated with the release of version 2.7? (I read through the
current NEWS file, but are there any more planned?).
