Hi. Far from complete, but some sketches on a solution is in the
Rdoc-to-Rd translator of the R.oo package. I, the author, never made
this very public because it uses a very ugly parser etc for it, but
the basics is there and I use it to generate \usage{} statements and
class hierarchies
Hi,
are there corresponding methods to exists() and get() where one can
stratify on class, e.g.
exists(..., inherits) instead of exists(..., mode)?
Thanks

Tried the following with R --vanilla on the Rv2.4.0 release (see
details at the end). I think the script and its comments speaks for
itself, but the outcome is certainly not wanted.
for (n in 58950:58970) {
cat(n=, n, \n, sep=);
# Clean up first
rm(names, x, y); gc();

However,
cat(\x7F\n\x80\n...\xFF\n)
works. Using R --vanilla.

Hi Benilton,
it is possible that this has to do with so called unevaluated
promises. I had a similar problem a few months ago. I emailed R-devel
about it - [Rd] save() saves extra stuff if object is not evaluated

I use the R.oo Object class for what has been suggested previously.
The Object class can be thought of as utility wrapper class for
environments (actually environments gained much of its behavior some
time ago when $ etc was being mapped to get() calls).
For caching to file, take a look at the

You need to explain what you mean by the question, for example
on.exit() applies to the function where it was called, i.e.
closeSomeServices() is called when .onLoad() exits, or whatever
function it is defined in. You're looking for .onUnload(). Make sure
to read the help for details.

Hi, without arguing for doing it or not, is the following a correct
way to reorder the search path:

Hi,
I noticed that serialize() gives different results depending on R
version, which has implications to the digest() function in the digest
package. Note, it does give the same output across platforms. I know
that serialize() is under development, but is this expected, e.g. is
there some kind

consistency between R version without loosing data dependent bytes.
Thanks
