function [out]=scattermap(long,lat,var1,var2,opt,varargin)
% PURPOSE: This function links a map and a two-dimensionnal scatterplot
%------------------------------------------------------------------------
% USAGE: out=scattermap(long,lat,var1,var2,opt,quantiles,qvar,carte,label,symbol)
%   where : 
%           long = n x 1 vector of coordinates on the first axis
%           lat = n x 1 vector of coordinates on the second axis
%           var1 = n x 1 vector of the variable to study on the first axis
%           var2 = n x 1 vector of the variable to study on the second axis
%           opt = parameter that tells how to draw the scatterplot
%                   * opt=1 : the scatterplot alone is drawn
%                   * opt=2 : a kernel mean estimator is added
%                   * opt=3 : quantiles are added ( see following optional parameter )
%           quantiles = optionnal vector of quantile orders to draw
%           qvar = qualitative variable
%           carte = n x 2 optionnal matrix giving the polygons of the edges of the spatial units
%           label = n x 1 optionnal variable used to label selected observations
%           symbol = * symbol=1 : selected spatial units are marked with a different symbol
%                    * symbol=0 : selected spatial units are marked with a different color only (default)
%------------------------------------------------------------------------
% OUTPUTS: out = (n x 1) 0-1 variable: selected spatial units are marked with a 1  
%------------------------------------------------------------------------
% MANUAL: Select points on either the map or the scatterplot by clicking with the left mouse button
%         You can select points inside a polygon: - right click to set the first point of the polygon
%                                                 - left click to set the other points
%                                                 - right click to close the polygon
%         You can select points that have the same qvar value by pushing buttons 0-9 on the keybord.
%         Selection is lost when you switch graph
%         To quit, click the middle button or press 'q'
