Dear Simon, The problem is that the recode specification is incorrect: In recode(), colons mean ranges, and shouldn't appear within c(), which is used to list values. See ?recode, and the following example:
> (green_2004_2 <- data.frame(french=runif(10, 0, 100))) french 1 42.693517 2 18.063822 3 21.046906 4 17.045596 5 9.308359 6 30.018840 7 53.598261 8 17.739567 9 65.836818 10 37.727236 > recode(green_2004_2$french, "50:100=0; 0:49.99=1") [1] 1 1 1 1 1 1 0 1 0 1 BTW, "50:100=0; 0:50=1" will produce the same result -- again see ?recode. Finally, it's generally a good idea to send a small reproducible example with a question like this. What if there were really a data-dependent bug in recode()?
