Hi Zhigang, AFAICT, I don't see `crossprod` as an exported symbol in `MatrixExtra`.
> library(MatrixExtra) > ls("package:MatrixExtra") Did you mean Matrix:: or base:: crossprod?

And in the NAMESPACE file, there is a row for "importFrom(MatrixExtra,crossprod)". So we are a bit confused why this error happened. And there was no error for the previous version. Would you mind providing some advice? Thanks.
