Hi !
I am trying to register. How to interpret the fax numer? Is it
+43 1 58801
or
+43 1 10798
I get a voice saying that these numbers do not exist?

Thanks for your response. I want to point out that I did try using the
nest=TRUE option earlier and got the same error with svydesign. I checked
and I was using version 0.9-1. I have updated this to version 1.0 and I am
no longer getting an error.
Your other suggestions work too

Dear R helpers,
I have a curious problem, which is that a program I have written in R
crashes R, unpredictably. When I say that the program crashes R, I mean
that it causes R to terminate, completely. But, the operating system

is there a function or way within R to solve A'A=S for A, where all
matrices have p x p order and S is a variance-covariance matrix?

Use eigen() or any of the principal component analysis functions.
If K has eigenvectors and D has eigenvalues, then A'=KD^{1/2} is
a orthogonal solution, and A=A'=KD^{1/2}K' is a symmetric solution.

That will work if S is unambiguously positive definite, but covariance
matrices need not be, and then chol (without pivoting) will fail.
Pivoting can be used: see ?chol.
A more expensive but safer solution is to use eigen: see the code for
mvrnorm.

The version I gave is obviously not vectorized (since your original version

Replacing is.null(n) with length(n)!=1 (or length(n)==0) should do the trick
(I hope!).
