zero_crossings {modelbased} | R Documentation |
Find zero-crossings and inversion points
Description
Find zero crossings of a vector, i.e., indices when the numeric variable crosses 0. It is useful for finding the points where a function changes by looking at the zero crossings of its derivative.
Usage
zero_crossings(x)
find_inversions(x)
Arguments
x |
A numeric vector. |
Value
Vector of zero crossings or points of inversion.

# plot(x, type = "b")
