Filter Genes By Expression Level

Determine which genes have sufficiently large counts to be retained in a statistical analysis. This is a similar function to edgeR::filterByExpr

ds.RNAseqPreproc(object, group = NULL, newobj.name = NULL, datasources = NULL)

Arguments

object

character Name of the eSet, RangedSummarizedExperiment on the server

group

character indicating the vector or factor giving group membership (optional).

newobj.name

character (default NULL) Name to be assigned on the server to the RangedSummarizedExperiment. If NULL the created RangedSummarizedExperiment will be assigned to a variable named 'rse.filter'

datasources

a list of DSConnection-class (default NULL) objects obtained after login

Value

This function does not have an output. It creates (or overwrites) a data frame on the study server.
