Scale Expression Values for Features (probsets, transcripts, genes)

Scale Expression Values for Features (probsets, transcripts, genes)

feature_scale(mat)

Arguments

mat	a numeric matrix with the expression values, where columns are the samples and rows are probesets, transcripts, or genes.

Value

scaled matrix

Examples

myexp <- t(sapply( 1:10000, function(i){ sample((0:12000)/1000,100) }))
myexp_scaled <- feature_scale(myexp)
par(mfrow=c(1,2))
boxplot(t(myexp[1:10,]), main='original')
boxplot(t(myexp_scaled[1:10,]), main = 'scaled')
