I have a string variable (V1) in a data frame structured as follows: V1 V2 A 5 a1 1 a2 1 a3 1 a4 1 a5 1 B 4 b1 1 b2 1 b3 1 b4 1
I want the following: V1 V2 V3 a1 1 A a2 1 A a3 1 A a4 1 A a5 1 A b1 1 B b2 1 B b3 1 B b4 1 B I am not sure how to go about making this transformation besides writing a long vector that contains each of the categorical string names (these are state names, so it would be a really long vector). Any help would be greatly appreciated.
