peakdet.RdDetect the peaks positions and valley positions. The algorithm is modified from github::dgromer/peakdet
peakdet(y, delta = 0, silence = TRUE)
| 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. |
A list with peakpos and valleypos. Both peakpos and valleypos are vectors of numeric which indicate the positions of peak or valley.
