Description Usage Arguments Value Examples

Description

filter.exp(train_mir, cutoff = 75, threshold = 0)

Arguments

train_mir

an expression matrix with miRNA in columns, samples in rows

cutoff

percentage of samples in which the miRNA should be expressed

threshold

the numeric threshold defining expression of miRNA. Default threshold = 0.

Value

filtered miRNA expression matrix

Examples

1
