[R] Generating MVN Data

[Rauf Ahmad]

Dear All

I want to generate multivariate normal data in R for a given covariance 
matrix, i.e. my generated data must have the given covariance matrix. I 
know the rmvnorm command is to be used but may be I am failing to 
properly assign the covariance matrix.

Any help will be greatly appreciated

thanks.
