AOI_seq {eyetools} | R Documentation |
Sequence analysis of area of interest entries
Description
Analyses the sequence of entries into defined AOI regions across trials. Can only be used with fixation data with a "fix_n" column denoting fixation events.
Usage
AOI_seq(data, AOIs, AOI_names = NULL, participant_ID = "participant_ID")
Arguments
data |
A dataframe with fixation data (from fixation_dispersion). Either single or multi participant data |
AOIs |
A dataframe of areas of interest (AOIs), with one row per AOI (x, y, width_radius, height). |
AOI_names |
An optional vector of AOI names to replace the default "AOI_1", "AOI_2", etc. |
participant_ID |
the variable that determines the participant identifier. If no column present, assumes a single participant |
Value
a dataframe containing the sequence of entries into AOIs on each trial, entry/exit/duration time into AOI
Examples
data <- combine_eyes(HCL)
fix_d <- fixation_dispersion(data, participant_ID = "pNum")
AOI_seq(fix_d, AOIs = HCL_AOIs, participant_ID = "pNum")
