balanceMatrixSize: Balance matrix dimensions

In NMikolajewicz/scMiko: scRNAseq analysis functions. Developed using Seurat framework.

Balance matrix dimensions

Description

Resamples two matrices to match number of rows in each. Number of rows is matched to minimum or maximum, as specified.

Usage

balanceMatrixSize(mat.1, mat.2, method = "match.max")

Arguments

mat.1	First input matrix.
mat.2	Second input matrix.
method	Character specifying which matching method to use. Must be one of "match.max" (default) or "match.min". For either option, matrix with min/max number of rows is resamples to match the other matrix.
s.mat	similarity matrix

Value

list of resampled matrices.

Examples

# ensure sample sizes are balanced across groups
output.mat <- balanceMatrixSize(de.orig.1, de.orig.2, method = "match.max")
de.1 <- output.mat[["de.1"]] # resampled mat.1
de.2 <- output.mat[["de.2"]] # resampled mat.2
datExpr.noz <- output.mat[["de.all"]] # concatenated matrices
