[datatable-help] recode variable regardless of its order

[Veda]

Hello experts,

I have two variables in a data frame, say "varA" and "varB".
varA: a, a, a, b, b, b, c, c, c
varB: a, b, c, a, b, c, a, b, c

What I want to do is to create two new variables like bellow
varA: a, a, a, *a*, b, b, *a*, *b*, c
varB: a, b, c, *b*, b, c, *c*, *c*, c

The point is to ignore whether the element is in varA or varB in the
recoding. I really appreciate any suggestion to achieve this. Thanks!

Veda
