featureAlignedSignal {ChIPpeakAnno} | R Documentation

## extract signals in given ranges

### 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` | Set the feature.gr to upstream and dwonstream from the center of the feature.gr if they are set.
`n.tile` | The number of tiles to generate for each element of feature.gr, default is 100
`...` | Not used.

### Value

A list of matrix. In each matrix, each row record the signals for corresponding feature. rownames of the matrix show the seqnames and coordinates.
