In benilton/oligoClasses-release: Classes for high-throughput arrays supported by oligo and crlmm

Description

Construct a GRanges object from several possible feature-level classes. The conversion is useful for subsequent ranged-data queries, such as findOverlaps, countOverlaps, etc.

Usage

makeFeatureGRanges(object, ...)

Arguments

object	A gSet-derived object containing chromosome and physical position for the markers on the array.
...	See the makeFeatureGRanges method for GenomeAnnotatedDataFrame.

Value

A GRanges object.

		gr <- grl[[1]]
		(frange <- makeFeatureGRanges(oligoSet))
		## which features overlap with the second range in sample NA06993
		subsetByOverlaps(frange, gr[2,])
