vi_permute reproducibility when using parallel processing

[balraadjsings]

Running vi_permute() with parallel=TRUE is not reproducible when using set.seed prior to running the function (have not tried other functions in the vip package but it'll probably also apply to them).

It seems set.seed() gets ignored while using parallel processing. Like my previous post, this also seems to be related to foreach. A fix I've found to work for now is to use the package doRNG instead of the set.seed() function e.g.:
registerDoRNG(seed = 123) and then run vi_permute() with parallel=TRUE

This might be something to note in the documentation for when parallelization is used?

Thanks @balraadjsings, added a link to your suggestion in the vi_permute help page! (Will push to the devel branch soon.)
