Changes in version 2.6.2:

    o   DMRcate pacakge get updated, Error like "Error in if (nsig == 0) :
	 missing value where TRUE/FALSE needed" has been solved.  In
	 champ.load(), instead of replacing all 0 and negative value into
	 0.0001, we relplace them as smallest positive now.  Fixed
	 warnings() in GUI() functions.  In champ.runCombat() function,
	 removed restriction on factors like Sample_Group. Also, added
	 "variable" parameter so that user may assign other variables other
	 then "Sample_Group".  Modified champ.DMR() function, for
	 ProbeLasso, there is no need to input myDMP anymore, ProbeLasso
	 function would calculate inside the function.  Added Demo on
	 github.
