Dear All,

I wonder how to re-code a categorical variable without using the ifelse loops. For example: Let X be a categorical variable with 6 levels, levels(X) = c(1,2,3,4,5,6)

How to create a new categorical variable Y with levels, 10,11,12, say , such that:

Y = 10 if X =1 or X=2 Y = 11 if X =3 or 4 Y =11 if X = 5 or 6

many thanks,

Bernard
