[R] recoding variables-recode not working

[John Fox]

Dear Vlatka,

It's impossible to know what the problem is without knowing something about
your data, which you didn't tell us either in this message or your
subsequent one.

The recode command should work:

> (x <- c(rep(0, 5), sample(1:30, 5, replace=TRUE)))
 [1]  0  0  0  0  0 17 27 19 19  2

> recode(x, "0='A'; 1:30='B'")
 [1] "A" "A" "A" "A" "A" "B" "B" "B" "B" "B"

The cut command requires include.lowest=TRUE and it helps to spell the
labels argument correctly:

> cut(x, breaks=c(0,1,30), include.lowest=TRUE, labels=c('0', '1 and more'))
 [1] 0          0          0          0          0          1 and more
 [7] 1 and more 1 and more 1 and more 1 and more
Levels: 0 1 and more

I hope this helps,
 John
