extracting covariances

[stephens999]

is there a function to get a list of the prior covariance matrices?
(meaning as a list of matrices; internally these are stored as a list of lists that is not really suitable for use in other packages)

I don't think so. We probably should revisit the interface, and in particular add a few useful functions (or S3 methods?) to make the package more accessible.

There is some code to extract covariance matrices, but not in a function. I am using:
U <- lapply(fit$U,function (e) "[["(e,"mat")). And I can write a function for this.

Please go ahead and do that @yunqiyang0215.

Added get_Ulist() here: https://github.com/stephenslab/udr/blob/master/R/misc.R

are these matrices, as stored, correctly scaled?
