peakdet {ATACseqQC} | R Documentation

## Detect peak positions

### Description

Detect the peaks positions and valley positions. The algorithm is modified from github::dgromer/peakdet

### Usage

    peakdet(y, delta = 0, silence = TRUE)

### Arguments

`y` | A vector of numeric where to search peaks
`delta` | A numeric of length 1, defining the local threshold for peak detection. If it is set to 0, the delta will be set to 1/10 of the range of y.
`silence` | logical(1). If false, echo the delta value when delta is set as 0.

### Value

A list with peakpos and valleypos. Both peakpos and valleypos are vectors of numeric which indicate the positions of peak or valley.
