Very few problems that are posed with a test dataset go unanswered.
the problem is that the new level "C" was not one of the original levels in $social status add "C" as a level and then just do the ol fashioned way and it works just fine do this: data$SOCIAL_STATUS <- factor(data$SOCIAL_STATUS, levels = c(levels(data$SOCIAL_STATUS), "C")) then this: data$SOCIAL_STATUS<-ifelse(data$SOCIAL_STATUS=="B" & data$MALE>4, "C", data$SOCIAL_STATUS) it is sooo much more helpful when someone who has addressed the specific problem being asked replies instead of people just throwing random ideas out there
Just a little Friday night trolling? This was a posting from 2 years ago.
