Suppose I have a tibble with some numerical variable that goes from a to b. For example:

```
my_df <- tibble(t = 835:1017)
```

I want to add a new `bin`

column like follows:

```
library(dplyr)
my_df <- tibble(t = 835:1017)
max_t <- max(my_df$t)
min_t <- min(my_df$t)
end <-min_t + 4*ceiling(length(min_t:max_t)/4)
out <- my_df %>%
mutate(bin = cut(min_t:max_t, breaks = c(seq(min_t, end, by = 4)), right = FALSE))
out
#> # A tibble: 183 x 2
#> t bin
#> <int> <fct>
#> 1 835 [835,839)
#> 2 836 [835,839)
#> 3 837 [835,839)
#> 4 838 [835,839)
#> 5 839 [839,843)
#> 6 840 [839,843)
#> 7 841 [839,843)
#> 8 842 [839,843)
#> 9 843 [843,847)
#> 10 844 [843,847)
#> # … with 173 more rows
```

Is there a tidier way of doing this?
