Hi Si Qi,
the above doesn't make a lot of sense, but I'll guess that you want to
convert your AppHomeStatus variable to a factor with "Owner occupier" as
the first level. Assume that the data frame is named "mydata".
mydata$AppHomeStatus<-factor(mydata$AppHomeStatus,
levels=c("Owner occupier","Living with parents",
"Private tenant", "Living with friends/family"))
If you have more levels, make sure that you add them to the "levels"
argument.
Jim
