Hi Alexandre,
Is there a preferred language you would like to use in your package
development? I randomly downloaded packages until I found some that
helped me along my way, and might be able to help you pick one. If you
are just looking at building a package of R functions and data you
have devel
Dear R developers
Would you consider adding a 'data.frame' method for the base::rep
function? The need to replicate a df row-wise can easily arise while
programming, and rep() is unable to handle such a case. See below.

Dear all,
Suppose the following code:
--8<--
mm <- function(datf) {
lm(y ~ x, data = datf)
}
mydatf <- data.frame(x = rep(1:2, 10), y = rnorm(20, rep(1:2, 10)))
l <- mm(mydatf)
-->8--
If I want to update l now without providing the data argument
It looks to me as though your proposal would allow update to remove
variables, but would give erroneous results when adding them. For example:
mm <- function(datf) {
lm(y ~ x, data = datf)
}
mydatf <- data.frame(x = rep(1:2, 10), y = rnorm(20, rep(1:2, 10)), z =
rnorm(20))
l <- mm(mydatf)

Howdy again Alexandre,
This sounds interesting and valuable, though might be touching some
areas of R that makes me think others should chime in. I have a
history of encouraging behavior that is sometimes not supported by the
general public. First search does not find a project currently trying
to

.. also note that there is Rserve PHP client (used, e.g., by FastRWeb) which
works around a lot of the issues you encounter when you try to embed R into PHP
(initialization cost, lack of thread-safety, no workspace separation etc.).
Cheers,

Good point. So let me rephrase the initial problem:
1.) An lm object is fitted

Hi,
Seems like this recent change broke the png() device:

Hi.
I am having difficulty following section 1.6.6 of the R-extensions manual.
I am trying to update the Brobdingnag package to include a NAMESPACE file (the
untb package requires the Brobdingnag package).
Without the NAMESPACE file, the package passes R CMD check cleanly.
However, if I include
Simon,
Thanx for your feedback.

Also in following the posting guide: which version of R is this (it
matters here!)?
It seems you are failing to import the functions you are attempting to
take over as S4
