get_velocity: get_velocity

In abeith/eyeCleanR: Clean and Transform Eye-Tracking Data

Description

get_velocity calculate the velocity of a vector using either the velocity from one point to the next or the method used in the saccades package which calculates velocity based on surrounding points.

Usage

get_velocity(x, smooth = 1, method = 1)

Arguments

x	vector of coordinates to calculate velocity between
smooth	number of leading points to smooth velocity by. If smooth = 1 the output will not be smoothed
method	the method to use. 1 is the velocity to the next point, 2 is based on both previous and next point but ignoring current point.

Value

Returns a vector of velocities

Examples

x <- sort(runif(5, 0, 10))
x <- c(x, rev(x))
get_velocity(x)
