[R] Question about cut()

[Tianchan Niu]

Dear all,
I would like to use cut() to make numerics to factors, the sample codes are as follows. However, the result is not what I want, since r[3] = 9 should be in the interval of "8-10%" rather than "2-4%". Maybe cut() is not the right function to use for my situation. Please help. > r <- c(1,1,9,1,1,1)
> col_no <- as.factor(as.numeric(cut(r,c(0,2,4,6,8,10,100))))
> levels(col_no) <- c("<2%","2-4%","4-6%","6-8%","8-10%",">10%")
> col_no
[1] <2%  <2%  2-4% <2%  <2%  <2% 
Levels: <2% 2-4% 4-6% 6-8% 8-10% >10%Thanks,
Tianchan
