Adding a column to a data.frame?

Question

I have the data.frame below. I want to add a column that classifies my data according to column 1 (`h_no`) in that way that the first series of h_no 1,2,3,4 is class 1, the second series of `h_no` (1 to 7) is class 2 etc. such as indicated in the last column. h_no h_freq h_freqsq 1 0.09091 0.008264628 1 2 0.00000 0.000000000 1 3 0.04545 0.002065702 1 4 0.00000 0.000000000 1 1 0.13636 0.018594050 2 2 0.00000 0.000000000 2 3 0.00000 0.000000000 2 4 0.04545 0.002065702 2 5 0.31818 0.101238512 2 6 0.00000 0.000000000 2 7 0.50000 0.250000000 2 1 0.13636 0.018594050 3 2 0.09091 0.008264628 3 3 0.40909 0.167354628 3 4 0.04545 0.002065702 3

Answer 1

library(dplyr)

res <- df %>% mutate(NEW_h_no=cut(h_no, breaks=c(1, 4, 7, 10), labels=c("Class1","Class2","Class3")))
