I'm looking to parallelise 2 sva functions:

num.sv: where B=20 indicates 20 permutations

num.sv(dat, mod, method="be", vfilter=NULL, B=20, seed=NULL)

sva: where B=5 is the no. iterations of the irw algorithm

sva(dat, mod, mod0=NULL, n.sv=NULL, controls=NULL, method="irw", vfilter=NULL, B=5, numSVmethod="be")

Is this possible using parallel or other parallelising package?
