Hi everybody!
I have a rather simple question:
# play data
persId<-c(1,2,3,1,4,5,2)
varA<-c(11,12,13,12,14,15,10)
df<-as.data.frame(cbind(persId, varA))
Now I'd like to create a new columns (df$new)
according to the value of df$VarA. For example
df$new1 should be 1 if df$varA==2 or df$new2 should
be 1 if df$varA>13.
I tried to do it like this:
if(df$varA==2) {df$new1<-1}
But, obviously, that's not how it works (I might be thinking to much in
mySQL: update table set new1=1 where varA==2).
How can I solve this problem using "if"?
I would not want to use recode() as my conditions might be more complicated
later on.
Thank you very much!
David
