I think the main advantage of a DVCS is that it allows many many
people to make changes to a project and to integrate those changes in
a non-insane way. Given that R as a very restricted list of people who
actually make changes to the source, it doesn't seem that something
like git or Hg would prov

What about NAof <- function(x) as(NA, class(x))?

I think using 'is(inEnv, "environment")' produces the answer you
expect. Can't explain the other anomalies though.

If I recall correctly, I thought indexing a vector/list with a
character vector uses hashing if the vector is over a certain length
(I can't remember the cutoff). Otherwise, it's a linear operation.

Given that the two functions (although identical) serve different
purposes and are in a sense unrelated, it's not clear that a See Also
is needed (and in fact might be confusing).

My advice would be to use the profiler 'Rprof()' --- you may find that
the loop is not really the problem. In my experience, there's
relatively little difference between 'lapply' and a 'for' loop,
although 'lapply' can be faster at times.

I usually use environments for this. So, in one of the R files for the
package, just do
.localstuff <- new.env()
Then, in functions you can do things like
.localstuff$bbg.db.conn <- dbConnect(...)

I built r44608 of R-devel with (I think) cairo support. At least,
that's what the configure script told me. In addition,

This is very nice work and I like it a lot. I think it would be quite

Okay, I wasn't sure if it was definitely related to rcompgen or was a

Upon replying to this email, I took a look at 'write.csv()' and noticed
something interesting. I remember there being a discussion sometime in
the past about letting 'write.csv()' accept the 'row.names' argument.
However, I get the following error:

If you don't want the row names, as 'write.csv()' writes out by default,
try
write.table(, file = "myfile.csv", sep = ",", row.names = FALSE)

If I'm not mistaken, when you put the other package in the "Depends:"
field of DESCRIPTION, the other package will be loaded first, before
your package is loaded. So you shouldn't have to put require/library
anywhere else.
