I'll do my best. Do you happen to know of a package that is doing this already, or doing something similar (so I could build on their code)?

@mwslawinska Could you please share some code we can use to reproduce the problem?

Which version of `RcppArmadillo` do you have?

Great! Thanks for letting us know.

@jhsiao999 Would it help to revise the documentation for `ash` and `ash.workhorse` to make this more clear for others? Or was it just that you didn't look in the right...
