In jashubbard/edfR: Basic functions for importing SR-Research Eyelink EDF files

Combine the results from edf.batch

Description

combine.eyedata can be used to take the results from edf.batch and stack into large data frames for fixations, saccades, etc.

Usage

combine.eyedata(batchdata, fields = c("fixations", "saccades", "blinks",
  "messages", "header"))

Arguments

batchdata	output from edf.batch
fields	character array of the particular fields you want to combine (default is c('fixations', 'saccades','blinks','messages')). Warning: combining samples will result in extremely large data frames (millions of rows per subject)

Details

edf.batch returns a list where each element has fields fixations, saccades, blinks, and (optionaly) samples. This function takes that result and creates a single data frame for all subjects' eye data

Value

a list with each of the requested fields. Each one is a data frame with all subjects' data. Subjects will be identified by the "ID" varaiable.
