[Rd] Problems with nlme (PR#471)

[berwin@maths.uwa.edu.au]

Dear R developers,

first of all let me join the chorus of congratulations for the release
of R 1.0.0.  Well, done!

Unfortunately, I find it necessary to e-mail in a bug report regarding
the `nlme' package.  On my office machine I experience the following
trouble:

bossiaea:/opt/R$ R CMD check -c nlme 
Checking package `nlme' ...
 Massaging examples into `nlme-Ex.R' ...
 Running examples in package `nlme' ...
 ERROR

The end of nlme-Ex.Rout is:

(R CMD check MASS is also failing on an example that uses update.gls.)

On my machine at home I run into troubles even faster when running `R
CMD check nlme'.  One of the early examples chokes on the line:
> data(Orthodont)

I had done a "clean install" on that machine, i.e., I first blew away
the older installation of R.  It seems that the datasets Orthodont and
Pixel have been distributed with the nls library in earlier R versions
but not so in R 1.0.0.  But they are not distributed with the current
version of nlme either.

Cheers,

        Berwin
