The loading time for MSnbase is quite long. I was wondering if we could reduce the package loading time (about 3.3 secs on my computer). This would be specifically helpful for parallel processing using SnowParam (only parallel processing available in Windows).

I guess the loading time is a combination of time spent on the imports and on the exports - so I guess there is not much that can be done.

It would be great if we could to that. Maybe worth exploring:

  • move some packages from depends to imports in the description
  • reduce import to importFrom in the namespace

I'll play a little around with that and what speed improvement we could get.

We could also review all Depends and Suggests. E.g. reshape2 is just used for melt (which could easily replaced), see #202 for example. (I am not sure whether @lgatto want to merge this now, or want to wait for the next release cycle).

As long as changes are relatively minor, like #202, I am happy to merge now.

I would rather like to change stuff later - don't want to break things again ;)
