Create a graph of adjacency based on the position of the channel

Source: R/position_to_graph.R

Create an igraph object defining adjacency of the channels. Adjacency is defined when 2 channels have a (Euclidean) distance inferior to delta.

position_to_graph(data, delta = 4, name = "name", x = "x", y = "y", z = "z")

Arguments

data

a data.frame containing the name and position of channels.
delta

a numeric defining the maximal distance for adjacency of two channels.
name

the column in the data containing the name of the channels.
x

the column in the data containing the X position of the channels.
y

the column in the data containing the Y position of the channels.
z

the column in the data containing the Z position of the channels.

Value

an igraph object.
