project3dMap: Project channel positions onto 2D plane

In tdeenes/eegR: Analyze EEG Signals

Description

project3dMap projects 3D coordinates onto a 2D plane or vice versa

Usage

project3dMap(
  pos,
  r = 1,
  projection = "laea",
  projref = c("pole", "equator"),
  origo = c(lat = ifelse(projref == "pole", 90, 0), long = ifelse(projref == "pole",
    270, 0)),
  inverse = FALSE
)

Arguments

pos	electrode positions (matrix or data.frame)
r	radius
projection	character string (default = "laea"). See http://www.remotesensing.org/geotiff/proj_list/ for common projections
projref	projection reference (pole [ = default] or equator)
origo	a named character vector of lat ( = latitude) and long (longitude)
inverse	if set to TRUE, back-projection is performed (default = FALSE)

Value

A data.frame containing the projected coordinates
