Hi to all,
I am having a problem when using recode from the car package. I have a variable that is char and when I use recode to create a new variable that is supposed to be numeric I get a factor variable. Here is the code I am using:
> FCI$PRE1 <- recode (PRE1RES, " c('C', 'c')=1 ; else = 0 ; as.factor.result=FALSE ")
So, if I understand correctly the recode command, the line above should create FCI$PRE1 variable with 1 if PRE1RES is c and zero otherwise. However, if I type
> FCI$PRE1[0]
I get as result:
factor(0) Levels: 0 1
FCI$PRE1 is not a numeric variable, and I get instead a factor. Recode seems to work fine as it correctly replaces the c's for 1 and other results for 0, but the fact that the recoded variable is a factor does not work for me.
Any suggestions on what I am doing wrong?
You're putting quotation marks around the argument is.factor.result as if it's part of the recode specifications. I believe that you want
FCI$PRE1 <- recode (PRE1RES, " c('C', 'c')=1 ; else = 0 ", as.factor.result=FALSE )
I hope that this helps, John
