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){

RAM usage
Hi,
I'm having problems while working with large data sets with R 1.5.1 in
windows 2000. Given a integer matrix size of 30 columns and 15000 rows
my function should return a boolean matrix size of about 5000 rows and
15000 columns.
First of all I tried to run this function on computer with 256 MB of
RAM. I increased memory limit of R with memory.limit() up to 512 MB. I
was inspecting

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
