Identifies local minima and maxima in a numeric vector using a sliding window of a given threshold. Used to detect changes in trend in smoothed hydrological data.
Usage
inflect(x, threshold = 1)
Arguments
- x
Numeric vector (e.g., smoothed discharge time series).
- threshold
Integer. Number of neighbors on each side to consider for identifying a local extremum.
Value
A list with two integer vectors: minima (indices of local minima) and maxima (indices of local maxima).
