Contains the example EEG data used in the package eegkit. Also contains code for easily creating larger EEG datasets from the EEG Database on the UCI Machine Learning Repository.
The data file eegdata
contains 64-channel EEG data recorded from 10 alcoholic and 10 control subjects. The funtion geteegdata
can be used to create larger EEG datasets from the EEG Database on the UCI Machine Learning Repository.

Contains 64-channel electroencephalography (EEG) data from 10 alcoholic and 10 control subjects participating in a visual event-related potential (ERP) experiment. Data frame contains 5 trials (replications) from each subject. Data were recorded at 256 Hz for 1 second following the presentation of the visual stimulus.
data(eegdata)
data(eegdata)

Creates a data matrix (observations by variables) from the EEG Database on UCI Machine Learning Repository. Data matrix has 7 variables: subject, group, condition, trial, channel, time, and voltage. See eegdata
and Details for more information.

Input directory (containing EEG data source folders). |
outdir |
Output directory (to save EEG data matrix file). |
cond |
Condition to read-in: S1=single stimulus, S2m=two matching stimuli, S2n=two non-matching stimuli. |
nt |
Number of trials to read-in for each subject (default is all trials). |
filename |
Name for EEG data matrix (default |
filetype |
Type of file to save (default is R data file .rda). |
EEG Database on UCI website contains 64-channel electroencephalography (EEG) data from alcoholic and control subjects participating in a visual event-related potential (ERP) experiment. Subjects were exposed to three experimental conditions: S1 single visual stimulus, S2m two matching visual stimuli, S2n two non-matching visual stimuli. Each subject participated in multiple trials (replications) of each experimental condition. Data were recorded at 256 Hz for 1 second following the presentation of the visual stimulus/stimuli.
Creates and saves a data matrix file.
