Like this?

x <- factor("001-014")
y <- substr(as.character(x), 1, 3)

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.

Is there an R function  or workaround to do this?
