hiReadsProcessor (version 1.8.2)

extractFeature: Extract a specific feature/attribute of the sampleInfo object.

Description

Given a sampleInfo object, the function extracts a defined feature(s) for given sample or sector.

Usage

extractFeature(sampleInfo, sector = NULL, samplename = NULL,
  feature = NULL)

Arguments

sampleInfo

sample information SimpleList object, which samples per sector/quadrant information along with other metadata.

sector

a vector or specific sector to extract the feature from. Default is NULL, which extracts all sectors.

Value

• a list or list of lists depending upon which parameters were supplied.
