Good morning!
I do not speak English very well and so I will try to explain the best I
can. I have this:
> tabela[,1]
[1] a a b b a c b a c c c c c
Levels: a b c
>unique(tabela[,1])
[1] a b c
Levels: a b c
>var<-unique(tabela[,1])[1]
> var
[1] a
Levels: a b c
But if I concatenate like this
> cat("VAR: ", var, "\n")
I obtain
>VAR: 1
and I want to obtain
>VAR: a
How can I do this? Thanks!
