[R] Plotting EEG signals as a "head" using R

[Charles Novaes de Santana]

Thanks a lot, Dénes!!

This library is very good! I can plot the head even in 3D using the command
"eegspace(space,voltage)", in which "space" defines the position of the
electrodes and voltage is the voltage of my EEG signal :)

Simple and elegant! :)

Thanks!

Best,

Charles
