centroid: Compute centroids

In tdeenes/eegR: Analyze EEG Signals

Description

centroid computes the centroids (separately for the negative and positive values)

Usage

centroid(dat, ch_pos, proj2map = TRUE, proj_unitsphere = FALSE, ...)

Arguments

dat	numeric vector of amplitudes at a given sampling point
ch_pos	matrix or data.frame containing channel positions (in the same order as dat), see coordinates
proj2map	logical value; if TRUE (default), the centroids are projected onto a 2D plane
proj_unitsphere	logical value; if TRUE, and proj2map is also TRUE, the projection assumes unit radius
...	additional parameters to project3dMap

Value

A data.frame containing the positions of the negative and positive centroids
