Filling Lists or Arrays of variable dimensions
Following problem:
Say you have a bunch of parameters and want to produce results for all combinations of those:
height<-c("high","low")
width<-c("slim","wide")
then what i used to do was something like this:
l<-list()
for(h in height){
l[[h]]<-list()
for(w in width){
l[[h]][[w]] <- doSomething()
}
}
Now those parameters aren't

Extract a predictors form constparty object (CHAID output) in R
I have a large dataset (questionnaire results) of mostly categorical
variables. I have tested for dependency between the variables using
chi-square test. There are an incomprehensible number of dependencies.
I used the chaid() function in the CHAID package to detect
interactions and separate out (what I hope to be) the underlying
structure of these dependencies for each variable. What typically

Dear R List,
I'm interested in modifying a regression tree algorithm to use the

I was wondering if anyone knew where I could find

AID / Tree Analysis in R
Dear Colleagues,
I've been looking for a function that can perform a tree analysis, similar to CHAID or QUEST. The key point is that in this case the variables are not binary but nominal (10 different values), so "tree" (from the tree package) won't work. Does anybody know help?
Sincerely,

Trees
Hi.,
I would like to conduct a CHAID tree analysis - Chi-square Automatic
Interaction Detector.
>From what I can make out from MASS, tree, rpart, and a quick search it
isn't available
as a package.
Is that correct or have I missed it? Has anyone an available
implementation of it?
Thanks

Newbie question - limit bandwidth of a link.

from PC2 to PC1. Is is possible to do this using iptables and tc

Disabling select instructions
I agree with John; also, if you decide to go this route, you can reuse the
code from CodeGenPrepare::optimizeSelectInst:

Is there any implementation of VSS for a ZFS iSCSI snapshot on Solaris?
I am using a Solaris + ZFS environment to export a iSCSI
block layer device and use the snapshot facility to take a snapshot of the ZFS
volume. Is there an existing Volume Shadow Copy (VSS) implementation on
Windows for this environment?
Thanks

[lld] support --trace-symbol option
I have submitted patch for "--trace-symbol=symbol" (alias -y symbol) option.
This option provides names of all the link time modules which define and
reference symbols requested by user. This helps to speed up application
development by detecting references causing undefined symbols. It also
helps in detecting symbols being resolved to wrong (unintended) definitions

Disabling select instructions
Hi,
I would like to know if there's a way to avoid select instructions during
the IR generation. What are the optimization passes that can result in a
select instruction?
i.e. I want to preserve branches in my code without disabling any other
optimizations applicable.
For example,
void foo(int* x, int* y){
if(*x > 0){
*y = *x + 10;
}
else{
*y = *x + 20;
}
}
