There is a mistake on the Weibull Distribution (base package) help
page in the online docs (http://docs.stat.ufl.edu/R/doc/html/). The
formula for Var(X) should have Gamma(1 + 1/a)^2 in place of Gamma(1 + 1/a).

That is a mistake at your own department's site, but not in the current R
sources. It seems those docs are from R 1.2.2! Even R 1.6.2 has the
correct formula.
Please ask whoever maintains that site to correct it, and don't expect the
R team to fix problems in 3.5 year old versions of R.

My g.data contributed package fails under R-devel. g.data creates minimal
packages which consist only of a DESCRIPTION file and the R and data
subdirectories, but .find.package() now rejects them because the DESCRIPTION
file lacks a Version field. I will fix g.data to add a Version field.
My
My question is, what else is necessary for a minimal package? Writing R
Extensions states:
The `Package', `Version', `License', `Description', `Title', `Author',
and `Maintainer' fields are mandatory...
So should I really add all these (superfluous) fields, to avoid future
rejection?

One of the changes some packages are noticing from the recent
modifications to methods is warnings of undefined classes during
installation when the package extends S3 classes or uses them as slots
UNLESSS they have been declared in a setOldClass() call. The green book

Jeff,
Does apache use threads? If it does, I would recommend *not* directly
putting R into the apache server for the simple reason that R is not
thread-safe.
You might find it simpler (and cleaner) to use the RSOAP
(http://rsoap.sf.net) interface to connect R with apache. I originally
created
Multi-threaded: No
Parallel: *Explicit* parallelism is supported if you use one of the
parallel libraries: rpvm, rmpi. The snow libraray provides a nice wrapper
for both / either of these.

There appears to be no is.formula() function in R-1.9.1. May I suggest
that
is.formula - function(x) inherits(x, formula)
be added to base, since formula is a fundimental R type?

why not just
is(x,formula)
?
