Code ageing methods to standardized character strings

Code ageing error methods to a set of standard character strings because some agencies use different codes for the same method. For example, break and burn can be "B", "BB", or 1.

codify_age_method(x)

Arguments

x

A vector that can be a mix of integers and characters.

A vector of characters.
