Re: [R] What is the correct way of using function C() for factors:

[Spencer Graves]

     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?
