I am tring to get a barchat by factors,
following the example in that link above.

===========================
x=c(145,40,40,120,180,
	140,155,90,160,95,
	195,150,205,110,160,
	45,40,195,65,145,
	195,230,115,235,225,
	120,55,50,80,45
	)

y2=c(
	rep(as.character(1),5),
	rep(as.character(2),5),
	rep(as.character(3),5),
	rep(as.character(4),5),
	rep(as.character(5),5),
	rep(as.character(6),5)
	)

barplot(as.matrix(x,y2),beside=TRUE,col=rainbow(5))
===========================

Why it does not seperate (by 'some' space) by the factors?
like not recognising the factors (1,2,3,4,5,6)?

Thanks.
