Added checks for snow and added it to suggests #1

This is since it is referenced in the manual in parallel but not in the description and hence isn't installed, but has to be installed manually and debugged.

Hi,

thanks for your commit, but I don't think is really needed. I have used and checked both the multicore fork approach and the snow psock approach and they work as expected in the current release of GA.

At https://cran.r-project.org/web/views/HighPerformanceComputing.html you can read: "Direct support in R started with release 2.14.0 which includes a new package parallel incorporating (slightly revised) copies of packages multicore and snow. " Note that parallel is on the list of suggested packages for GA.

If you don't agree please provide a simple, reproducible example, where snow is not working as expected.

What is really missing is the support for a user defined cluster, perhaps created with Rmpi. It is on my list of things to do, so hopefully in the future.

Best,

Luca

Yep no worries.
