Hello Group,
I could use an advice on how SEXP handles work. My aim is to implement a
system where I initially set a few global variables that are used for
communication between C and R code. Then I do some work with R code and
periodically call a function of my own that will update the system

Thomas,
Thank you for your response. I checked the FAQ and it provides an example
using sqrt(2) where you'd expect numerical precision to be an issue.
I guess that I expect R to act pretty much as C or C++ would do if I were to
program the same code. It's a bit of a surprise that assignment o

It's a FAQ, not a bug. Consider:

Dear r-devel,
Using the latest R-devel from SVN, when doing a make install, even
from a build directory, there is a recursive copy that attempts to
copy the .svn file to the framework include directory. The problem is
due to the fact that there is a reference to $srcdir in Makefile.in

Hi,
I am not sure if this is the right place to report a small typo in one of
the manuals. It is not really a bug, is it?.
In any case, at the end of section 11.6.2 (the glm() function) in the
Quasi-likelihhod models subsection there is an example of using the glm
procedure to fit a particular n
I'd like to iterate my earlier request (#7737) to change the documentation
for bxp().
The argument outpch=" " needs to be replaced with outpch=NA in two places.
I actually wrote this part of the documentation myself at one point, but
have now realized that pch=NA and pch=" " are not the same:

Please supply a reproducible example as both the FAQ and the posting
guide do ask.

It would be easy to add 'yaxs' support to bxp(), which can aid visual
comparison when the lower limit is zero. The two lines from boxplot.R that
would change are:
plot.window(ylim=c(0.5,n+0.5), xlim=ylim, log=log)
to
plot.window(ylim=c(0.5,n+0.5), xlim=ylim, xaxs=pars$yaxs, log=log)
and

This seems strange. I have a small block of code that repeatedly calls rbinom.
I put a break in there in case it returns NaN, as I've been having problems with
this. Here is a transcript from the debug ses

Thanks Gabor,
Yes, I know that works, but I want the function coca.formula to accept a
formula like this y2 ~ y1, with both y1 and y2 bei
It can handle data frames like this:

Hi I'm having a problem with model.frame, encapsulated in this example:
