Hi, Is it a requirement to provide the break intervals of the cut function in ascending order? The help documentation for cut didn't specify this but the labels returned are reversed if I indicate the break intervals in a descending order. Here is an example
tbl<-data.frame(x=c(0:10)) tbl$ascending<-cut(tbl$x, breaks=c(0,3,5,9,99), labels=c('<3','4-5','6-9','>9'), include.lowest=T) tbl$descending<-cut(tbl$x, breaks=c(99,9,5,3,0), labels=c('>9','6-8','4-5','<3'), include.lowest=T) tbl x ascending descending 1 0 <3 >9 2 1 <3 >9 3 2 <3 >9 4 3 <3 >9 5 4 4-5 6-8 6 5 4-5 6-8 7 6 6-9 4-5 8 7 6-9 4-5 9 8 6-9 4-5 10 9 6-9 4-5 11 10 >9 <3 Appreciate any guidance on this.
