Usage:	`cartdrawpdfclass(VarMatrix,ClassVector,SplitRule,MinSize, FilePath)`
Input:
	`VarMatrix`	n x m matrix, variables
	`ClassVector`	n x 1 vector, classes
	`SplitRule`	scalar, splitting rule either 0 (Ginni) or 1 (Twoing)
	`MinSize`	scalar, stop condition, minimum number of observations in terminal node
	`FilePath`	Complete path to the file, including the name of the file, e.g. c:\tree.tex

Example:

library("xclust"); x = #(1,2,3,4,40,50,60,80,90, 100, 110, 300, 500)~#(10,0,40,60,100,1,-91,20,20,34, 1, 3, -5); y = #(1,1,1,1,2,1,1,2,3,2, 3, 3, 3) //Plot tree in TeX //Change for the appropriate file name here: filename = "c:\ClassificationTree.tex" cartdrawpdfclass(x,y,1,1, filename);

Result:

Generates TEX file. Can be then compiled Tex->PS->PDF (Not Tex -> PDF)
