% eegplot2event() - convert EEGPLOT rejections into events
%                   compatible with the eeg_eegrej function for rejecting 
%                   continuous portions of datasets.
%
% Usage:
%   >> [events] = eegplot2event( eegplotrej, type, colorin, colorout );
%
% Inputs:
%   eegplotrej - EEGPLOT output (TMPREJ; see eegplot for more details)
%   type       - type of the event. Default -1.
%   colorin    - only extract rejection of specific colors (here a n x 3
%                array must be given). Default: extract all rejections.
%   colorout   - do not extract rejection of specified colors.
%
% Outputs:
%   events     - array of events compatible with the eeg_eegrej function 
%                for rejecting continuous portions of datasets.
%
% Example:
% NEWEEG = eeg_eegrej(EEG,eegplot2event(TMPREJ, -1));
