custom_ia: Map gaze data to newly defined interest areas

In VWPre: Tools for Preprocessing Visual World Data

Description

custom_ia uses a lookup data frame to map Left and Right gaze data to newly defined/supplied interest areas for each recording event. The lookup data should contain columns Event, IA_LABEL, IA_ID, Top, Bottom, Left, Right, which specify the Interest area label, its corresponding ID, and the boundaries (in pixel values) for each recording event. The function will overwrite existing columns RIGHT_INTEREST_AREA_LABEL, RIGHT_INTEREST_AREA_ID, LEFT_INTEREST_AREA_LABEL, and LEFT_INTEREST_AREA_ID.

Usage

custom_ia(data, iaLookup = NULL)

Arguments

data	A data table object output by prep_data.
iaLookup	A data frame object containing by-event mapping information.

Value

A data table object.

Examples
