readPointsOfInterestFile {Basic4Cseq}R Documentation

Read a file with coordinates of marker points

Description

This small helper function reads a tab-separated file with points of interest information stored in a BED-like format. The file has to provide the columns "chromosome", "start", "end", "name" and "colour" of the regions. The data can then be used for marking the points in near-cis visualization plots, as provided by visualizeViewpoint and drawHeatmap.

Usage

readPointsOfInterestFile(poiFile)

Arguments

poiFile

Name of the input file (tab-separated)

Value

Data frame with information on points of interest for the near-cis visualizations
