Dear Alain,
Taking a stab in the dark here but I find that if my original column is
a factor then recode won't work for me. Would a simple ifelse statement
not do the same thing?
test$variable <- ifelse(test$x>=1 & test$x<=5,0,1)

Dear Alain,
I'm afraid that I can't duplicate your problem. First, there is no recode
function in the Rcmdr package; it uses recode from car.
Here's a record of my Rcmdr session, using the recode dialog to generate the
recode command:
test$variable<- recode(test$x, '1:5=0; else=1; ', as.factor.result=TRUE)
test # entered in script window
x variable
1 1 0
2 2 0
3 3 0
4 4 0
5 5 0
6 6 1
7 7 1
8 8 1
9 9 1
10 10 1
I noticed that you set as.factor.result=TRUE for one command and FALSE for
the other, but both work for me. It occurred to me that you may have entered
the recode command in the script window and executed it from there, but that
works for me too.
Best,
John

Subject: [R] Problem with the recode function
Hello,
I am using the recode() function in Rcmdr and the result is not what I
expect so I am almost sure I did something wrong but what...
> test<- data.frame(x=1:10)
> library(car)
> recode(test$x,'1:5=0 ; else=1', as.factor.result=TRUE)
[1] 0 0 0 0 0 1 1 1 1 1
Levels: 0 1
BUT
> library(Rcmdr) # recode from the car package is now masked
Now I recode test$x through the Rmcdr interface and I get the following
code :
test$variable<- recode(test$x, '1:5 = 0; else = 1; ',
as.factor.result=FALSE)
And a vector of NA as result.
> test$variable
[1] NA NA NA NA NA NA NA NA NA NA
I am using R 2.11.1 with Rcmdr 1.5-5 on Windows Vista.
Regards,
Alain
