Using a loop to define new variables
Hi,
I'm a novice R user, much more used to SAS. My problem is pretty simple - basically, in a data frame, I have variables named
x1,....,x10 and y1,...,y10; and I would like to create r1 = x1 / y1 etc
Apologies if this is way too rudimentary - but I couldn't find any posts online which solve this exact issue.
Cheers,
Andre

ARCH LM test for univariant time series
Hi,
Does anyone know if R has a Lagrange multiplier (LM) test for ARCH
effects for univariant time series?
Thanks!

Manipulation of data.frame into an array
Hello everyone,
I want to transform a data.frame into an array (lets call it mydata), where: mydata[[1]] is the first imputed dataset...and for each mydata[[d]], the first p columns are covariates X, and the last one is the outcome Y.
Lets assume a simple data.frame:
Imputed = data.frame( X1 = c(1,2,1,2,1,2,1,2, 1,2,1,2,1,2,1,2),
X2 =

sem R: singular and Could not compute QR decomposition of Hessian
Can somebody help me with the following issue (SEM in R), please:
When I run the model (includes second order models) in R, it gives me the following:
1) In sem.default(ram = ram, S = S, N = N, param.names = pars, var.names = vars, :
Could not compute QR decomposition of Hessian.
Optimization probably did not converge.

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:
