msplit {batch}

Split Vectors for Parallelization

Description

Aids in splitting of a vector for parallelization, e.g. splitting up a group of SNPs into subgroups, so each one can analyzed in a parallel process. Other uses might be to choose splitting points for k-fold cross validation.

Usage

msplit(vec, m)

Arguments

vec

A vector, e.g. c(1,2,3), 1:10.

m

Numer of splits.

Details

Returns a list, with each member being a subgroup to be parallelized.
