By default, 20 labels (or up to 40 see below) are shown. If the number of items is less than twice the number of desired labels, all labels will be shown (to avoid irregular holes for some labels). I.e. if n=20, and x has 22 entries, there would be only two labels removed, giving a very irregular picture. It only becomes somewhat regular if after any label there is at least one blank, i.e. at most half the entries are labeled. #' Example: ## p is any ggplot object p + scale_y_discrete(breaks = ggAxisLabels) ## customize 'n' my.ggAxisLabels = function(x) ggAxisLabels(x, n = 4) p + scale_y_discrete(breaks = my.ggAxisLabels)
