[datatable-help] append two factor vectors

[el_alisio]

Hi,

how about:


q1 <- c("a1", "a2" ,"a3")
q2 <- c("b1", "b2", "b3") 
as.factor(c(q1, q2))

In case q1 and q2 are already factors, first convert them into characters:

q1 <- as.factor(q1)
q2 <- as.factor(q2)
as.factor(c(as.character(q1), as.character(q2)))

Cheers,

Jannes
