I am not able to understand the below behavior of cut.
> data = seq(0,1,.2)
> data
[1] 0.0 0.2 0.4 0.6 0.8 1.0
> cuts = cut(data, c(0, 0.25, 0.5, .6, 0.9, Inf))
> summary(cuts)
(0,0.25] (0.25,0.5] (0.5,0.6] (0.6,0.9] (0.9,Inf] NA's
1 1 0 2 1 1
As per my understanding the intervals made by cut are closed on right. Thus the interval (0.5,0.6] should have one element (.6) instead of zero. Similarly interval (0.6,0.9] should have 1 element only instead of 2.
Where am I wrong.
