Description

Calculates column mean and variance. Adapted from pagoda2. https://github.com/kharchenkolab/pagoda2/blob/main/src/misc2.cpp

Usage

colMeanVars(sY, rowSel, ncores = 1L)

Arguments

sY	sparse matrix Gene by cell matrix of counts
rowSel	numeric The selected rows (genes)
ncores	numeric The number of cores

Value

data.frame with columns of mean, variance, and number of observeatios for each gene across samples

Examples

library(Matrix)
donor_by_gene <- rbind(c(9,2,1,5), c(3,3,1,2))
donor_by_gene <- Matrix(donor_by_gene, sparse = TRUE)
result <- colMeanVars(donor_by_gene, rowSel = NULL, ncores=1)
