downsample

<code>downsample</code> reduces the sampling rate using median values for the
Pupil and gaze coordinates.

Pupillometric data collected using SR Research Eyelink eye trackers
requires significant preprocessing. This package contains functions for
preparing pupil dilation data for visualization and statistical analysis.
Specifically, it provides a pipeline of functions which aid in data validation,
the removal of blinks/artifacts, downsampling, and baselining, among others.
Additionally, plotting functions for creating grand average and conditional
average plots are provided. See the vignette for samples of the functionality.
The package is designed for handling data collected with SR Research
Eyelink eye trackers using Sample Reports created in SR Research Data
Viewer.
