Strange behaviour of post-legalising optimisations(?)
I come across a situation that I am having a hard time to understand.
When I compile the following code :
char *tst( char *dest, const char *src, unsigned int len )
{
for (int i=0 ; i<len ; i++) {
dest[i] = src[i];
}
return dest;
}
Clang generates this for the ‘for’ body:
for.body: ; preds = %for.cond
%arrayidx = getelementptr inbounds i8,

Boxplot questions.
Dear all,
I am having a data for 2 different treatments with
different time points. So, I used the following code
to plot the boxplot and also to do anova.

T12 <- c(400, 397, 285, 407, 313)

Matrix inversion
I cannot find what is the function label for matrix inversion in R. I have
found 'ginv' for the moore-penrose in the MASS package, but there is
probably a simple inversion operator in the base package. Where can I find
it?

Re-Post: Combining Factors in model.matrix
Hello,
I didn't get any response on this before, leading me to believe I've missed
something fundamental. Can anybody guide me in the correct direction for more
help on this?

Installing packages
Hello,
I have upgraded from Mandrake Linux 8.0 to Mandrake 8.1 and try to reinstall
my favourite R... Everything is OK for the base software but I have trouble
to get some packages installed.
Specifically, for some packages, a "collect2" binary seems to be necessary
during the compilation/linking process of the library, and LD complains about
not finding it :

[SelectionDAG] Assertion due to MachineMemOperand flags difference.
Hello,
I've hit an assertion in SelectionDAG where we try to merge 2 loads
that have the same operands but their MMO flags differ. One is
dereferenceable and one is not. I'm not sure what the underlying issue
here is:
1) MDSDNode with the same operands should have the same flags set on
their respective MMO. The fact the flags differ when the
opcode,types,operands and address-space are

Item Response Analysis
Hello,
Would someone have ever heard or developed any Item Response Models library
for R ? Of course, a Rasch model can be estimated through glm() but it is not
the case for more complex (polytomous) response models.
Similarly I would be interested in any R implementation of nonlinear
multivariate analyses a la GIFI (HOMALS, PRINCALS, OVERALS).
Thanks a lot in advance,

Given that this is compiled with -O0, would there a way to skip the

Installing ESS under EMACS
Dear members,
I have spent some time to make clear how I could write R programs from within EMACS using the ESS package, under Win98. Unfortunately, I have found this not quite clear for Windows 98 (though a lot of details are provided for UNIX).
I have tried to create a .emacs file with a command such as (load "PATH/ess-site.el") and also added a "PATH=...\rw1010\" line in

llvm-dev Digest, Vol 166, Issue 22
Hi Krzysztof,
Sure, please see below. DAG.dump.() before and after, annotated with what I
believe the DAG means.
I've spent some time debugging the method but it's proving difficult to
determine where the logic is misfiring. Disabling the entire combine causes
a lot of failing x86-64 tests - I may have to learn an upstream vector ISA
to make progress on this.
Thank you

New package announcement: R2STATS, a GUI for fitting GLM and GLMM
Dear R-users,
I wanted to inform you that a new package called R2STATS is available,
as a graphical front-end for the glm() and glmer() functions.
The GUI is based on the RGTk2 and gWidgets packages by Michael Lawrence
and John Verzani, and so requires that the GTK+ library be installed
first on your system. This is done "automagically" when installing the

Instruction selection problems due to SelectionDAGBuilder
