Add column which contains binned values of an integer column

Question

I have a dataframe with a few columns, one of those columns is ranks, an integer between 1 and 20. I want to create another column that contains a bin value like \"1-4\", \

Answer 1

We can use smart_cut from package cutr :

# devtools::install_github("moodymudskipper/cutr")
library(cutr)

Using @Andrie's sample data:

x$bins <- smart_cut(x$rank,
                    c(1,5,11,16), 
                    labels = ~paste0(.y[1],'-',.y[2]-1), 
                    simplify = FALSE)
# rank  name   info  bins
# 1    1 steve    red   1-4
# 2    3   joe   blue   1-4
# 3    6  john  green  5-10
# 4    3   liz yellow   1-4
# 5   15   jon   pink 11-15
