[R] How to find the variance-covariance matrix of a random-vector using R

Dear All, Reposting as plain text rather than html. I realized that R does not support finding the variance-covariance matrix of a random-vector. It must take two arguments. Numpy's cov doesn't give sensible results. I ask in a bigger context of finding the variance-covariance matrix of the ve
