I have a simple chart:
barchart(Counts ~ Purchase | Products , data = my.data, groups = Model)
where Purchase in data has values {0,1,2,3...10}. In a chart xlab begins with 1 not 0. How to change it?
I guess that barchart() will coerce Purchase to be a factor with levels '1' to '10'. So make it a factor with your choice of levels: PurchaseF <- factor(Purchase, levels = 0:10) (or use the scales= argument in barchart()) -Peter Ehlers
Best, Robert
