check_index {experDesign}

Check index distribution on batches

Description

Report the statistics for each subset and variable compared to the original.

Usage

check_index(pheno, index, omit = NULL)

Arguments

pheno

Data.frame with the sample information.

index

A list of indices indicating which samples go to which subset.

omit

Name of the columns of the pheno that will be omitted.

Details

The closer the values are to 0, the less difference is with the original distribution, so it is a better randomization.

Value

A matrix with the differences with the original data.

                        sex = c("Male","Female"))
check_index(metadata, index)
