I have a factor variable that is 6 digits and hyphenated. For example, 001-014.
I need to extract the first 3 digits to a new variable using mutate in dplyr -
in this case 001 - but can’t find a function to do it.
substr will do this for character strings, but I need the variable to remain as
a factor.
What prevents you from calling as.factor() on the result to turn it
back into a factor?
H.
Is there an R function or workaround to do this?
