Very few problems that are posed with a test dataset go unanswered.

most all those posts were right in sourcing the problemits just that
nobody actually offered a viable solution
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

I'm afraid that ifelse has very bizarre semantics when the yes and no
argument
Explicitly convert it to a factor...
data$SOCIAL_STATUS<-factor(ifelse(data$SOCIAL_STATUS=="B" & data$MALE>4,
"C", data$SOCIAL_STATUS))
However, note that this would, in general, change the levels attribute to
the levels actually present in the converted vector. If you wish to (and it
makes sense
You can work with levels of factor:
levels(DF$SOCIAL_STATUS)[DF$MALE > 4 & DF$SOCIAL_STATUS == "B"] <- "C"
