Creating labels for multiple levels

So I have a data frame with multiple levels, shown below:

> levels
54 42 30 18 17 19  6  5 NA 78  4

I need to label these into 4 different groups 

> labels
 "0-1" "1-2" "2-3" "3+"

I'm trying to use the following code, but I need the levels to be the same length as the labels. How do I do that? 

df$y <- cut(df$x, levels, labels)

May be cut can be useful

cut(levels%/%12+1, breaks=c(-Inf, 1, 2, 3,Inf), labels = c("0-1", "1-2", "2-3", "3+"))
#[1] 3+   3+   2-3  1-2  1-2  1-2  0-1  0-1  <NA> 3+   0-1 
#Levels: 0-1 1-2 2-3 3+

data

levels <- c(54, 42, 30, 18, 17, 19, 6, 5, NA, 78, 4)
