[R] subset drop unused levels

hi there tried to use subset with drop=TRUE, but all the 'old' levels are preserved, i.e. when calling e.g. ftable a lot of zeros are displayed x-subset(LREG, (kir=='AA' | kir=='BB') (type=='t1' | otype=='t2'), drop=TRUE, select=c(event, kir, type)) ftable(x) i explicit have to call factor
