Downsample gaze

Description

This function downs-samples gaze by a specified factor. Data are down-sampled by splitting the data in bins and calculating the mean of each bin.

Usage

downsample_gaze(data_in, ds.factor, xcol = "x", ycol = "y")

Arguments

data_in	Data frame which must contain the variables specified by the parameters xcol and ycol.
ds.factor	The factor to down-sample by. For example, setting ds.factor to 10 down-samples data recorded at 1000 HZ to 100 HZ.
xcol	Name of the column where raw x values are stored. Default: x
ycol	Name of the column where raw y values are stored. Default: y

Value

Data frame with downsampled gaze data. The output variables are x, y, and the numbers of the first and last samples of the original data frame included in the bin.
