Matrix: how to re-use the symbolic Cholesky factorization?
I have been playing around with sparse matrices in the Matrix
package, in particularly with the Cholesky factorization of matrices
of class dsCMatrix. And BTW, what a fantastic package.
My problem is that I have to carry out repeated Cholesky
factorization of a spares symmetric matrices, say Q_1, Q_2, ...,Q_n,
where the Q's have the same non-zero pattern. I know in this case one
does

Dear list,
I have problems installing R-2.0.1 on SUSE Linux 9.2. I used the

Error in X11(): X11 is not available.
I do have a running

Improving efficiency in "outer"-like calculation
Hello,
I am doing mcmc=10000 simulations from a posterior distribution of the parameters
of a mixture of K=6 normal densities.
I have mcmc by K matrices simMeans, simVars and simWeights containing
the simulation output: one row for each simulation, one column for
each normal component of the mixture.
One thing I would like to do is a plot of the posterior predictive
density. In order to do that
