In abc-igmm/transcripTools: Collection of functions for analysing gene expression data

Description

mostVar Calculate the top n most variable genes in a matrix of gene expression data

Usage

mostVar(data, n, i_want_most_var = TRUE)

Arguments

data	An expression matrix (samples in columns, genes in rows)
n	The number of variable genes to return
i_want_most_var	Logical value to return most variable (TRUE) or least variable (FALSE) genes

Value

A subset of n most variable rows from the original data

Examples

#synthesise example data matrix
mtx <- matrix(rnorm(mean = 7, n = 90), ncol = 10) 
row.names(mtx) <- LETTERS[1:9]

mv_3 <- mostVar(data = mtx, n = 3)
