Description

extract signals in the given feature ranges

Usage

featureAlignedSignal(cvglists, feature.gr,  upstream, downstream,  n.tile=100, ...)

Arguments

cvglists

List of SimpleRleList or RleList

feature.gr

An object of GRanges with identical width.

upstream, downstream

upstream or dwonstream from the feature.gr. It is used for x-axis label.

n.tile

The number of tiles to generate for each element of feature.gr, default is 100

...
