Thanks to all for your excellent suggestions. I think will I proceed
working through the Stroustrup book. He has a section on comparing C
with C++ and one on working with legacy C code that may prove helpful. I
also have a "C for Dummies" (something like that, I don't have it right

Thank you so much for your great answers, and I apologize for using
obsolete versions and not being up to date on all the posts.
My native linux R is indeed R-2.3.1 which was also the version for
which I successfully cross-compiled. When trying to cross-compile for
2.4.0 and 2.4.1 I was not succes

The 2.4.0 issue has been well documented only last week, in the thread
https://stat.ethz.ch/pipermail/r-help/2007-January/123303.html
as well as in an answer I had already posted.
I am almost certain the issue for 2.4.1 is user error. Remember you need
to set in MkRules

is there an argument for including a version check on R startup? These

Please, use the current version of R and not an obselete one (you failed
to report the version, but you do have 'R-2.4.0' in the path name, so I
presume that is what you are using). This does not occur under 2.4.1.

Mark,
Great question. As Gabor said, if it is "just for R", there is no point in
learning C or C++. However, learning new programming paradigms is very useful
in and by itself, and being able to extend R with C, C++ or Fortran is
extremely useful for R.
I would suggest what I jokingly call 'C+'
Thank you!
It's clear now. I was not looking at the real source code, but at the
code you get from the print method (that is by simply typing combn
at the prompt), which has all the comments removed. Next time I'll
take my time looking for the real source code ;)
Thanks again,
Giampiero
On Fri,
The usual drill: The problem is fixed in R 2.4.1 (i.e. please do
not report bugs on old versions). In addition, you need newer mingw
than you have.

You missed my posts (earlier this week). The subject is:
"mingw-cross with R 2.4.x Re: [Rd] wine and build difference between
R.2.4.0 and R 2.4.1 windows binaries?" which contains my notes on this
subject.
Basically you need newer mingw than on Prof Ripley's web site (i.e.

You don't necessarily need to know C or C++ to write an R package.
Many (maybe most) R packages only use R.

as.integer(1) would perhaps be the more pedagogical way to program this.

Dear all,
I already posted a question regarding this to an existing thread:

that might be illuminating.

I have the same problem, trying to cross-compile.
I'm running Ubuntu Edgy, kernel 2.6.17-10-generic, on an IBM T60.
I downloaded the Makefile from CRAN and ran make CrossCompileBuild
with the following error messages (also ran each make one at the time
and the problem occurs in make R):

Hi,
I was checking the source code to the function combn that "generates
all combinations of the elements of 'x' taken 'm' at a time.",
because I wished to modify it. I have a doubt about a statement.
This is the main loop.
._1 <- 1:1
nmmp1 <- n - m + ._1
