I have a data frame with a category
column.
For each class within the category
column, I would like a repeating sequence from 1 to n
. For example, in the below table, for each unique value in the category
column (e.g. a
, b
, c
etc.), I would like to have a repeating sequence from 1 to 3
in the corresponding sequence
column
id |

a |
