sttkymdfreq {stabilo}R Documentation

Quantifies the Median Frequency of the Anteroposterior Displacement of COP.

Description

Computes the median frequency of the anteroposterior displacement of the center of pressure.

Usage

sttkymdfreq(dados, sampfreq)

Arguments

dados

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

sampfreq

number The sampling frequency

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.

Value
