recode_to(dummy)

# recode 3-6 to 0-3
# note that numeric type is returned
dummy <- as.factor(3:6)
recode_to(dummy)

# lowest value starting with 1
dummy <- sample(11:15, 10, replace=TRUE)
recode_to(dummy, 1)

# lowest value starting with 1, highest with 3
# all others set to NA
dummy <- sample(11:15, 10, replace=TRUE)
