Dense EEG Cap Coordinates

Description

Dense (hypothetical) three-dimensional electroencephalography (EEG) electrode coordinates, and corresponding projection onto two-dimensional plane. Dense cap spans the 84 scalp electrodes defined in eegcoord.

Usage

data(eegdense)

Format

A data frame with 977 observations and the following 5 variables:

x

x-coordinate of 3d cap (numeric).

y

y-coordinate of 3d cap (numeric).

z

z-coordinate of 3d cap (numeric).

xproj

Projected x-coordinate of 2d cap (numeric).

yproj

Projected y-coordinate of 2d cap (numeric).
