cvSubsets: cvSubsets

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

Examples

library(curatedOvarianData)


data(E.MTAB.386_eset)





set.seed(8)


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





subset1 <- E.MTAB.386_eset[, id[[1]]]


subset2 <- E.MTAB.386_eset[, id[[2]]]


subset3 <- E.MTAB.386_eset[, id[[3]]]





## 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 <- list()


subsets[[1]] <- E.MTAB.386_eset[, id2[[1]]]


subsets[[2]] <- E.MTAB.386_eset[, id2[[2]]]


subsets[[3]] <- E.MTAB.386_eset[, id2[[3]]]


subsets[[4]] <- E.MTAB.386_eset[, id2[[4]]]


subsets[[5]] <- E.MTAB.386_eset[, id2[[5]]]
