Would it be possible to enhance this error message? Could the message say
how large the limit was that was reached? Is it that the limit for one
particular vector has been exceeded (and to how much would it have grown
vs. how much was allowed?), or is it that the entire memory space has been
estfun( sample[.index, , drop=FALSE] ))
message("never gets here with mclapply")
print( do.call("c", o[[1]]) )
print( do.call("c", o[[2]]) )

Apologies for the Intrusion. I am trying to learn package development with
roxygen. The ecosystem has been moving so fast that much of what I learned
by googling and reading on the web (including old posts) seems to be at
least mildly outdated.
* does the r-package-devel mailing list have a
variant looks even nicer,
is.matrix(m) %or% m is not a matrix but a {{class(m)}}
but requesting base R to add the %and% and %or% (or, better yet, 'and'
and 'or') operators by default would be pushing my luck.

[the {{...}} had the advantage of being unlikely to break anything.
perl has it nicely done--- is interpolated, ' is not. but this is a
bridge that we crossed long ago in R. it would break too much.]

thx. would be happy to do this, but is it worth the effort? are you guys
interested in potentially chasing this down or is this mundane?

check multiple aspects at the

different type than an integer? it's a little confusing. how about
defining a strictly positive integer?

to improve. but the strictness
of R seems too lax right now, making error tracking too difficult,
from the perspective of an end user. this is partly why I suggested a
more general bounty to improve on this aspect of R, rather than on my
specific issue(s).

in the documentation for by, please change the See also section to
\seealso{\code{\link{tapply}}, \code{\link{simplify2array}},
\code{\link{ave}}}

thank you, simon. this was very interesting indeed. I also now
understand how far out of my depth I am here.
fortunately, as an end user, obviously, *I* now know how to avoid the
problem. I particularly like the as.list() transformation and back to
as.data.frame() to speed things up without
. (if the index table
is there, it could be used. otherwise, R could simply use the
existing internal mechanism.)
I think faster data frame access would significantly improve the
impression that R makes on novices. just my 5 cents.

suggestion is still to issue an ambiguity warning when

I just figured out what is happening. The root drive (presumably OSX
virtual memory) becomes depleted. The error message about memory not
mapped was a hint, too. So, not really R's fault. However, I wonder
whether R can be made to abort more gracefully, or at least trap the
error message and
-(whatever) ## ok
just a suggestion...

hi gabor: this would be difficult to do. I don't think you want to
read my programs. it would give you an appreciation of what ugly
horror programs end users can write in the beautiful R language ;-).

dear R developers:
may I suggest that you add to the various error messages that relate to
non-conformable arguments (e.g. matrix multiplication) or not
multiple of(e.g., comparison) the actual two dimension numbers that do
not match up? something like
Error in t(a) %*% vcov(reg.model) :
Dear Brian / Thomas:
May I suggest a cheap and amateurish solution, obviously without much
knowledge or intelligence about the subject?
As a non-statistician user of R, maybe a hook functionality at strategic
places could provide some flexibility without too much pain. I think
