Give means of rows of matrix based on column grouping variable

Description

Inspired by edgeR::sumTechReps and base::rowsum(), this function takes the average of the values in each group given by the group argument for each row of the data matrix.

Usage

colmean(x, group, na.rm = FALSE)

Arguments

`x`	variable (gene) by sample numeric matrix
`group`	Factor specifying the grouping level to by averaged
`na.rm`	Logical (TRUE or FALSE). Should NA (including NaN) values be discarded?

Value

variable x nLevels(group) matrix

Examples

# Specify the Group levels
Group <- gl(n = 2, k = 3, labels = c("DMSO", "THZ1"))

# Take the average of every gene by treatment group
by_group <- colmean(GSE161650_lc, group = Group)
by_group[1:5, ]
