Cut and labels/breaks length conflict

Question

I am working with the cut function to prep data for a barplot histogram but keep running into a seeming inconsistency between my labels and breaks:

Error in cu

Answer 1

With cut(), 11 breaks delimit 10 levels which will require only 10 labels. The "labels/breaks length conflict" error is telling you that the call to sprintf() is supplying one too many labels to the labels= argument.

In code:

breaks <- 0:10/10
dat <- runif(1e4)

length(breaks)
# [1] 11
length(levels(cut(breaks, sq)))
# [1] 10
