| cvSubsets {simulatorZ} | R Documentation |
To generate a list of subsets(indices of observations) from one set
cvSubsets(obj, fold)
obj |
a ExpressionSet, matrix or RangedSummarizedExperiment object. If it is a matrix,columns represent samples |
fold |
the number of folds in cross validation. Number of observations in the set does not need to be a multiple of fold |
returns the list of indices of subsets
