Finds the local maxima in a vector, or time series, or in each column of a matrix.
Usage
peaks(x, span=3, strict=TRUE)
Arguments
x
vector or matrix.
span
a peak is defined as an element in a sequence which is greater than all other elements within a window of width span centered at that element. The default value is 3, meaning that a peak is bigger than both of its neighbors. Default: 3.
strict
logical flag: if TRUE, an element must be strictly greater than all other values in its window to be considered a peak. Default: TRUE.
Value
an object like x of logical values. Values that are TRUE correspond to local peaks in the data.
