sttkveloc: Velocity of a Center-of-pressure displacement

Description

Computes the mean velocity of a given Center-of-pressure displacement in the horizontal plane.

Usage

sttkveloc(dados, fs)

Value

The velocity of the COP displacement sttkveloc.

Arguments

dados

Data frame with two columns "x" and "y"

fs

The sampling frequency used in data recording

Examples

x <- c(1,3,7,5,9,4,3,6,8,2,8,9,4,5,7,3,4,7,9,3,2,5,3,4,8,2,9,7,4,2)
y <- c(6,3,9,1,3,7,4,9,6,1,7,3,9,7,2,6,3,4,8,1,9,3,6,8,1,6,2,9,8,3)

COP <- data.frame(x, y)
fs <- 50

COPvelocity <- sttkveloc(COP,fs)
