Hi Ana,

Thanks for your question, which is now approved in the forum. The error you got indicated that there was not enough RAM to be used for this particular R computation. We suggest you to:

1. Use the latest version of R (64-bit).

2. Increase the limit on the memory uses by using command-line flag --max-mem-size (see FAQs on http://cran.r-project.org/ )

3. If the design matrices are sparse, covert them to sparse matrix object by using Matrix package before using then in hglm.

4. Remove any unnecessary objects from your current workspace.

Best wishes,
hglm developers
