project_elecs: Electrode projection

In neuroconductor/eegUtils: Utilities for Electroencephalographic (EEG) Analysis

Electrode projection

Description

Project a set of 3D Cartesian co-ordinates to a 2D plane for plotting. The projection can be orthographic or stereographic. Orthographic is closer to how the scalp would look from above, since it does not compensate for height/distance from the xy plane. This causes bunching up of electrodes near the limits of the head. Stereographic preserves more of the general shape of the features by "unrolling" the electrode positions.

Usage

project_elecs(chan_info, method = "stereographic")

Arguments

chan_info	Channel information from an eegUtils object
method	Method of projection. "stereographic" or "orthographic". Defaults to sterographic.
