which is quite something different. But this will convert a potentially huge factor to character and back to factor which may be resource intensive. Does anyone here know a simpler way of achieving this, i.e. given f, without using as.character()?
Does this help?
factor(levels(f)[f], levels = c("c","b","a"), labels = c("cc","bb","aa"))
