getting/storing the name of an object passed to a function
Hi
I have a couple of functions that work on the object created by another R
command and then print out or summarise the results of this work.
The main function is defined as:
hotelling.t <- function(obj)
{
#internal commands
}
I then have print.hotelling.t() that takes the list returned by hotelling.t
and prints it with some extra significance calculations, formatting, etc.
I want to

Error: system is computationally singular: reciprocal condition number
I get this error while computing partial correlation.
*Error in solve.default(Szz) :
system is computationally singular: reciprocal condition number =
4.90109e-18*
Why is it?Can anyone give me some idea ,how do i get rid it it?
This is the function i use for calculating partial correlation.
pcor.mat <- function(x,y,z,method="p",na.rm=T){
x <- c(x)

Reciprocal Update
If I run "rsync -ruv <local> <remote>" twice, no files are copied the
second time - as expected. However, if I follow "rsync -ruv <local>
<remote>" with "rsync -ruv <remote> <local>", all files are copied from
<remote> to <local>.
I suspect this is because the timestamps of <remote> files are of when

[LLVMdev] Proposal: New DAG node type for reciprocal operation
Sounds like a reasonable fit for a target-specific DAG combine. I suspect a target specific node wouldn't be necessary and the patterns could be matched directly.

[LLVMdev] Proposal: New DAG node type for reciprocal operation
Hi,
In relaxed/fast math mode, if we can convert a/b to a * (1/b), we may get
more performance when (1) "b" is loop invariant or (2) arch has faster
reciprocal instruction (e.g. recipe/recips on ARM) or (3) arch has no
vector div, but has vector mul and recip.
So ,with this node type, a div node can be converted to a mul and a recip
when desired. Then, each arch can further

Graphics Reciprocal labeling

Reciprocal Mill's Ratio
I believe that this may be more appropriate here in r-devel than in r-help.
The normal hazard function, or reciprocal Mill's Ratio, may be obtained
in R as dnorm(z)/(1 - pnorm(z)) or, better, as dnorm(z)/pnorm(-z) for
small values of z. The latter formula breaks dowm numerically for me
(running R 2.4.1 under Windows XP 5.1 SP 2) for values of z near 37.4
or greater.
Looking at the pnorm

[LLVMdev] Proposal: New DAG node type for reciprocal operation
Yes, what I mean is a target independent node in the ISD::NodeType enum.
I already did the node transformation DAGCombiner and target-specific lowering in the first place. It worked. But introducing a specific node will make the logic more clear.
For example, in ARM, FDIV is a scalar operation. So, after DAGCombiner and Vector Type legalize, vectorized FDIV has been expanded into scalar versions,

smbd has memory leak
Hi,
I am running smbd ver 1.9.16P9 on QNX
when I do a find computer from a windows NT box and start clicking I see
smbd 's DATA szie increase...but after I kill( close) all windows explorer
tasks on the Windows NT box.. smbd still has the same DATA size....It does
not free up memory....

I'm trying to conduct sensitivity analysis in R using the 'sensitivity' package. Although the description of functions seem straightforward, I can?t succeed. The definition of input factors can be the problem.
