sttkxveloc: Mean lateral velocity of Center-of-pressure displacement

Description

Computes the mean lateral velocity of a given Center-of-pressure displacement.

Usage

sttkxveloc(dados, fs)

Value

The lateral velocity of the COP displacement sttkxveloc.

Arguments

dados

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

fs

The sampling frequency used in data recording

Details

'dados' is a data frame containing two columns named "x" and "y". The pairs (x, y) are the coordinates of the center-of-pressure acquired in a period of time.

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

COPxvelocity <- sttkxveloc(COP,fs)
