FXListBox size behavior?
The default behavior of FXListBox seems to be to grow and shrink in
width depending on the length of the selected entry in the list. This is
a problem when the list contains items of varying width, because if a
short item is picked then the longer entries are obscured in the
drop-down list.
Is this deliberate, an oversight, or a bug? Its certainly not how I''d
choose it to act. Is

Tcltk changes in R 1.8.0
I have committed a set of changes to the tcltk package for R-1.8.0.
The most important changes are
1) Support for Tcl arrays, which should come in handy for people
playing with things like the tkTable extension. Basically these
work like tclVar objects but can be subscripted (notice that these
beasts are associative - like a Perl hash - rather than objects of
set dimensions). Basic

returning an empty list.
I would like to return an empty list from a C function. This I would do as:
if (file.exists()) {
/* do something */
}
else {
SEXP empty_list;
PROTECT(empty_list = NEW_LIST(0));
UNPROTECT(1);
return empty_list;
}
The PROTECT, UNPROTECT lines seemed like overkill to me, but as far as I
understood the documentation this seemed like the correct usage. It
seems like I could

How to return a big treelike list from .Call Interface (protect stack overflow)
I try to create a big treelike list structure using the RDefines/RInternal
macros. The tree carries information at each node (attribute list) and at each
leaf (vector).
My understanding is that for each node I add to the binary tree I have to
call
PROTECT(newnode = NEW_LIST(2));
and cannot UNPROTECT before I return the whole tree. Same story for node
attributes and leaf vectors. However, this

protect
I have a few simple questions about the usage of PROTECT, more
specifically how careful one needs to be. Simple yes/no answers are
fine.
Most of the uses I have seen do protection when memory is allocated.
But what if one just want to assign a value of another function to a
variable. Say eg. that foo is a function that returns a SEXP. Would
the following code be fine?
SEXP bar;

not safe to return vector pointer
Hello All,
I recently upgraded from R-1.1.1 to R-1.2.2.
I have an R function that uses .Call() to
return a list from C code. The C code
has the form:
SEXP function(SEXP var)
{
SEXP rlist ;
PROTECT(rlist = NEW_LIST(3)) ;
VECTOR_PTR(rlist)[0] = NEW_INTEGER(1) ;
VECTOR_PTR(rlist)[1] = NEW_STRING(1) ;
...
UNPROTECT(1) ;
return(rlist) ;
}

allocation of large matrix failing
Hello, this is probably something silly which I am doing, but I cannot
understand why this allocation is not happening.
Here is a my C code which tries to allocate a list of size 333559, and
then a matrix of size 8*333559
I thought I might be running into memory problems, but R is not even
using that much (I start R with
more memory and it stays constant) Also, I start R as I normally do and

C++: SET_LENGTH() Over Many Iterations?
In a C++ extension to R (v 1.8.1), I've been experimenting with a
generic "push back" function to tack one value at a time onto the end
of an R vector created within the extension. After calling this
function a certain number of times Rgui.exe (I'm writing in Windows
using Visual Studio .NET 2003) will fail with an Access Violation,
which doesn't happen when I pre-allocate

Call and memory
I use a large real matrix, X, in C code that is passed from R and
transposed in place in the C code. I would like to conserve memory and,
if possible, allocate space for only one copy of X -- hence I would like
to pass a pointer to the data in the X object to the C code.
The Writing R Extensions manual says that neither .Call nor .External
copy their arguments. They also say that these

gdmgreeter and powersave
I have a bunch of workstations running CentOS 5.2. When the gdmgreeter is displayed, the monitor never blanks or powers off even though I have DPMS enabled in xorg.conf. When a user is logged in it works as expected. I Googled around and saw some references to this happening, but have not found a solution. Am I missing something obvious?

SWIGging ConfigBase
Hi all
I''m trying to write an .i file for ConfigBase. If I can figure out a few
general SWIG things then I think most of it will work. Apols for the
noob swig questions.
The C++ class has lots of overloaded methods called Read, which return
different kinds of values. In wxruby-not-swig these are implemented as
read, read_bool, read_int and so on. read() means read_string(). In ruby
