getV.spline: Get splined velocity estimates

In EliGurarie/smoove: Simulation and Estimation of Correlated Velocity Movement (CVM) Models

Get splined velocity estimates

Description

Computes the locations and velocities of a cubic spline of a 2D track over time.

Usage

getV.spline(Z, T.raw, T.new = NULL, resolution = 0.01, ...)

Arguments

Z	location data in complex form (X + iY)
T.raw	time of observations to feed the spline.
T.new	new time vector
resolution	of spline, i.e. the fraction of the smallest interval in T.raw.
...	further arguments to splinefun. Importantly, the method.

Value

a list with the estimated velocity (V), as well as the position (Z) and time (T).

Examples

data("Kestrel",package = "smoove")
Z <- with(Kestrel, X+1i*Y)[1:500]
T <- Kestrel$timestamp[1:500]
vsp <- getV.spline(Z,T, resolution = 1e-2, T.new = NULL)
str(vsp)
