peakdet: Detect peak positions

In ATACseqQC: ATAC-seq Quality Control

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.
