cvSubsets: cvSubsets

In zhangyuqing/simulatorZ: Simulator for Collections of Independent Genomic Data Sets

Description

To generate a list of subsets(indices of observations) from one set

Usage

cvSubsets(obj, fold)

Arguments

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

Value

returns the list of indices of subsets

Examples

library(curatedOvarianData)


data(E.MTAB.386_eset)





id <- cvSubsets(E.MTAB.386_eset, 3)


subsets <- lapply(1:3, function(i){E.MTAB.386_eset[1:10, id[[i]]]})


sapply(subsets, dim)


rm(subsets)





## Number of observations in the set does not need to be a multiple of


## the fold parameter


id2 <- cvSubsets(E.MTAB.386_eset, 5)


subsets <- lapply(1:5, function(j){E.MTAB.386_eset[1:10, id2[[j]]]})


sapply(subsets, dim)


rm(subsets)
