repr_pla {TSrepr}

PLA representation

Description

The repr_pla computes PLA (Piecewise Linear Approximation) representation from a time series.

Usage

repr_pla(x, times = 10, return = "points")

Arguments

x

the numeric vector (time series)

times

the number of important points to extract (default 10)

return

what to return? Can be "points" (segments), places of points (segments) in a vector ("places") or "both" (data.frame).

Value

the values based on the argument return (see above)
