extrema: Create Local Extrema Object

In mjfii/Local-Extrema: Calculate and Visualize Local Extrema

Description

This function returns an S3 class, 'local.extrema', which contains local maxima and minima, the interval used to derive those extrema, and a data frame with xy coordinates that may be used for plotting.

Usage

extrema(x, interval, min_per_change = NA)

Arguments

x	A numeric vector or integer vector for use in determining local extrema.
interval	An integer value to specify the degree to which changes in local extrema should be calculated and identified.
min_per_change	A numeric value denoting the minimum change to recognize a reversal. Default value is NA. NA treated as there is no minimum for reversal.
