lapply() reccursively
Hi all,
I was wondering whether it is possible to use the lapply() function
to alter the value of the input, something in the spirit of :
a1<-runif(100)
a2<-function(i){
a1[i]<-a1[i-1]*a1[i];a1[i]
}
a3<-lapply(2:100,a2)
Something akin to a for() loop, but using the lapply() infrastructure.
I haven't been able to get rapply() to do this.
The reason is that the "real"

RSpython Ubuntu
Dear List,
I'd like to call pyhton function from within R. I tried installing the latest
version of RSPython:

R CMD INSTALL --clean RSPython_0.7-1.tar.gz
I get a compile error (posted below).
Did anyone else run against this ? Is there a solution ?

C source code question (Robustbase edition)
Hi all,
I have been trying to add the line:
h = n - p0 + 1;
just after
h = n / 2 + 1;
(line 131) in the source code (the original paper mention this is possible
for p0<n).
with p0 declared as an int (actually i used the same declaration
protocol as n everywhere in the code).
The "new" source compiles, but when i give it reasonable
values of p0, it runs unto

Rmath library problems
Hello,
Has anybody successfully called the Rmath library from C using the MS
Visual Studio compiler (I am using Visual Studio 6.0)?
I have compiled the Rmath library using gcc, and the 'test.c' program
(which makes a call to qnorm) works fine when compiled with gcc. However,
I get a fatal memory error when I run it after compiling it with Visual C.
Would this memory problem be related

GPU packages and 'Debian R Policy'
Hi there,
Moving this request for info over from an R-HPC-SIG list thread as
the issue is less HPC than something that has bitten me as a result
of trying to install HPC (read CUDA) R packages.
Background to this is that I have both a Ubuntu host for a Tesla card
that some researchers are looking to do CUDA-related R computation on,
and a prototype, RHEL-based, cluster that is being used to

Rglpk
Hi list,
in the Rglpk_solve_LP function (::Rglpk),
on line 26, the function calls a function
as.glp_bounds() that i cannot access.
i'm trying to alter the Rglpk_solve_LP function
to add a line to retrieve column/row dual values.
everytime i change the slightest line of code inside
Rglpk_solve_LP() [to even add a print]
i get a
': could not find function "as.glp_bounds"'

defines in Rmath.h and R_NO_REMAP
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Hi,
I'm programming with R 2.7.2 and had some trouble including
Rmath.h for its random variates generation routines: Although
I define R_NO_REMAP (which works fine for Rinternals.h stuff),
Rmath.h defines "beta" as "Rf_beta" etc., so that my "beta" strings
get redefined as well! Is this a feature?

Rmath.dll importing in VB6 problem
Hi,
I am facing a problem which i think i need to explain it to you with some
background.
I need to use the Project R pnorm function in Visual Basic 6.0.
I have already installed R and this is how i perform and get back the
result:
> pnorm(2, 15)
[1] 6.117164e-39
which is what i need.
I have already installed R, i generated the Rmath.DLL file out so i can
import it into my VB6 and use it.

Making rmath.dll (or equivalent)
I currently have R 2.12.1 installed, both 32 and 64 bit. I also have a file
that was passed to me named rmath.dll. I do not know what version of R it
was created from, but I do know it is 32-bit only. I am developing an
application in C# that uses this library as a reference but I have to
downgrade it to 32-bit in order to use the DLL file.
I wish to make a rmath.dll from the version of R I have

cross-compiling + expm1
Hello all,
Just joined this mailing list -- not sure if this is the right list to
send this question, but I have a question about cross-compiling R. I am
working with R-1.9.1.tgz.
It may just be with my version of mingw32, but it seems that expm1 is
not defined, so I tried to ensure that HAVE_EXPM1 was #undef'ed before
cross-compiling. The problem is that, in <include/Rmath.h> if

question on suppressing error messages with Rmath library
Dear list,
I have been using the Rmath library for quite a while: in the current instance, I am calling dnt (non-central t density function) repeatedly for several million. When the argument is small, I get the warning message:
full precision was not achieved in 'pnt'
which is nothing unexpected. (The density calls pnt, if you look at the function dnt.) However, to have this happen a

makefile for standalone lib
It appears the Makefile.win in
src/nmath/standalone might need some modification since
cd src/nmath/gnuwin32
make -f Makefile.win
make -f Makefile.win test
fails. However if I remove libRmath.a from line 15
OR
modify lines 67/68 replacing Rmath.a with libRmath.a then
make -f Makefile.win test
goes as expected.

No Rmath.h when making just standalone library
When making only the standalone math library, include/Rmath.h
is not there, so compilation fails. A solution is to go to
src/include/ and just say `make Rmath.h' there first.
This is with R-2.2.0 on GNU/Linux on i686. The failing steps
are:
tar xzf ../R-2.2.0.tar.gz
./configure
cd src/nmath/standalone
make
Would be nice if this worked, or if the issue were just

xyplot() does not plot legends with "relation=free" scales
Hi all,
I have this problem with lattice that xyplot() won't draw some of my axis labels if the type (i.e. the relation argument) of scales is set as free. For example, in the plot below, I would want it to also show:
1. the labels E1,...E6 below the 10th panel (i.e. 3rd row, 2 col)....just as it is now done below the 12th panel....
2. as well as the labels (2,4,6,8) on the top of panels 1
