plot_velocity_profiles: Create ggplot of saccade velocity profiles

In kollaR: Filtering, Visualization and Analysis of Eye Tracking Data

Create ggplot of saccade velocity profiles

Description

This function plots and returns a ggplot showing velocity profiles of saccades plotted against time. Saccades should be generated with the ivt.filter functions with the save.velosity.profiles parameter set to TRUE. The interval to plot is defined by saccade number as they appear in the sacccades data frame.

Usage

plot_velocity_profiles(saccades, onset = NA, offset = NA, verbose = TRUE)

Arguments

saccades	data frame including saccades. Each saccade must have a list with a vector of the veloctity profiles
onset	first saccade to plot. The value must correspond to a number in the variable "number" in the saccades data frame. If left empty, all saccades are plotted
offset	last saccade to plot. The value must correspond to a number in the variable "number" in the saccades data frame.
verbose	If TRUE, print the resulting plot

Value

ggplot with velocity profiles

Examples

new.plot <- plot_velocity_profiles(sample.data.saccades, onset = 10, offset = 20)
