filterConsensus | R Documentation |
Filters lowly expressed peaks from down-stream analyses
filterConsensus( cp, filter.method = "custom", library.threshold = 2, cpm.threshold = 1 )
cp |
consensus peak matrix, with unique ids at rownames. |
filter.method |
filtering method for low expressed peaks |
library.threshold |
number of libraries a peak occurs so that it is not filtered default set to 2 |
cpm.threshold |
count per million threshold for not to filter a peak |
returns differentially accessible peaks
set.seed(123) cp <- matrix(rexp(200, rate=.1), ncol=20) ## using cpm function from `edgeR` package cp.filtered <- filterConsensus(cp)
