Below I have tried to paste a path and file name but it will not work
> path <- "D:/rw0641/own/own/procedures/GFR_TIME"
> path
[1] "D:/rw0641/own/own/procedures/GFR_TIME"
> path1 <- paste(path,"gfr.txt",sep="/")

Problem of COX model with time dependent covariate
Hi all,
I am trying to detect association between a covariate and a disease outcome using R. This covariate shows time-varying effect, I add a time-covariate interaction item to build Cox model as follows:
COX <- coxph(as.formula("Surv(TIME,outcome)~eGFR_BASE+eGFR_BASE:TIME"),ori.data);
coef exp(coef) e(coef) z p
eGFR_BASE 6.40 603.5133 0.3702 17.3 0
eGFR_BASE:TIME -3.41 0.0329 0.0772 -44.2 0
But the result seems very different from that go...

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
