Gaze data from the Visual World Paradigm requires significant preprocessing prior to plotting and analyzing the data. This package provides functions for preparing visual world eye-tracking data for statistical analysis and plotting. It can prepare data for linear analyses (e.g., ANOVA, Gaussian-family LMER, Gaussian-family GAMM) as well as logistic analyses (e.g., binomial-family LMER and binomial-family GAMM). Additionally, it contains various plotting functions for creating grand average and conditional average plots. See the vignette for samples of the functionality. Currently, the functions in this package are designed for handling data collected with SR Research Eyelink eye trackers using Sample Reports created in SR Research Data Viewer. While we would like to add functionality for data collected with other systems in the future, the current package is considered to be feature-complete; further updates will mainly entail maintenance and the addition of minor functionality.

======================
### Overview
This package provides tools for preprocessing and plotting Visual World Paradigm data.
Currently, it is built to accommodate data collected with SR Research Eyelink eye trackers.
However, we hope to provide functionality for other eye-tracking systems in the future.
### Installation
You can install the currently released verion of the package from CRAN as follows:
install.packages("VWPre")
### Usage
Example usage of specific functions contained in the package can be found in the vignettes.
These documents are organized thematically and walk users through the steps needed to preprocess and visualize data from an SR Research (Eyelink) sample report.
You can view the available vignettes as follows:
