Extract fixations

Source: R/extract_fixations.R
extract_fixations.Rd

Extracts fixations from the events table of the eyelinkRecording object. Normally, you don't need to call this function yourself, as it is called during the read_edf with default settings (e.g., import_fixations = TRUE).

Usage

extract_fixations(object)

# S3 method for class 'data.frame'
extract_fixations(object)

# S3 method for class 'eyelinkRecording'
extract_fixations(object)

Arguments

object

Either an eyelinkRecording object or data.frame with events, i.e., events slot of the eyelinkRecording object.

Value

Object of the same time as input, i.e., either a eyelinkRecording object with an additional fixations slot or a data.frame with fixations' information. See eyelinkRecording for details.

gaze <- extract_fixations(gaze)

# by passing events table
fixations <- extract_fixations(gaze$events)
