WISH: Formal package tests

[HenrikBengtsson]

Hi, thanks for working on this. I should also say that I'm not a user of the package, but I'm interested in HPC for R in general.

I'd like to suggest that you add package tests to your package to increase the confidence in the package. It would be helpful if these would compare the results (ideally near numerically equal) to standard R alternatives, e.g. hclust(). You can probably take several of your example() code and turn the into package tests as a start.

If this package can "promise" numerical similarities to standard solutions, I think it increases the chances for the package to be used as an optional tool, iff supported. Almost like automatic parallel processing via mcapply() et al. with automatic fallback to lapply() when no parallel backend is available.

Just some thoughts. Cheers.
