What is the correct way of using function C() for factors:
To combine objects that are already factors, the solution I've
found is to first coerce them to mode character:
> F1 <- factor("a")
> F2 <- factor("b")
> factor(c(as.character(F1), as.character(F2)))
[1] a b
Levels: a b
hope this helps.

The funciton c() works differently for strings and for factors: For strings:
l = c('a', 'b')
l
[1] "a" "b" For factors:
l = c(factor('a'), factor('b'))
l
[1] 1 1
What should be the right technique for merging factors?
