[R] Problem with recode -Error in parse(text = range[[1]][1]) : unexpected end of input in c(0
Dear colleagues, in the help archive there was a previous person who encountered a problem with the recode command in the car library. I'm not sure if that was solved, there was no posting to that effect, but I'm having the same problem. I'm trying to recode a numeric variable with values from 0-100 into a binary variable with values (0,1). The following command: recode(green_2004_2$french, c(50:100)=0; c(0:49.99)=1) gets the following error message Error in parse(text = range[[1]][1]) : unexpected end of input in c(0 I tried it with a second numerical variable in the same data set, but get precisely the same error at precisely the same location in the command, i.e. the second colon. As far as I can tell I have the most up-to-date version of car installed. Any suggestions? Yours, Simon Kiss * Simon J. Kiss, PhD SSHRC and DAAD Post-Doctoral Fellow John F.

Re: [R] Problem with recode -Error in parse(text = range[[1]][1]) : unexpected end of input in c(0
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()?

Dear David, Thank you for addressing this question, but I answered Simon's question in an email I sent to the R help list a while ago: You can't mix : and c() in a recode specification; : isn't the sequence operator in a recode specification but rather represents a continuous range of values. Thus, something like 0:49.99=1 is perfectly line, but c(0:49.99)=1 isn't.
