Hello, Guys! Could someone help me with this?
If i have a function...
funcao <- function(x){
Z <- x*3
}
i can do this... and it works
vector <- c(1,2,3)
Resultado <- funcao(vector)
I want to use the information of a tibble as argument to that function, like this...
tibble <-tribble(
~letras, ~numeros,
"a", c(1,2,3),
"b", c(2,3,4)
)
Resultado <- funcao(tibble[1,2])
What about if i have it in a string? Like this..
string <- text = "c(1,2,3)"
Resultado <- funcao(string)
Can somebody help me, please?
Thank you!

One way to do this is to modify the function to work with different kinds of input.
funcao <- function(x){
if(!is.vector(x))x <- unlist(x)
x*3
}
tibl <- tibble::tribble(
~letras, ~numeros,
"a", c(1,2,3),
"b", c(2,3,4)
)
funcao(1:3)
#> [1] 3 6 9
funcao(tibl[1,2])
#> numeros1 numeros2 numeros3
#> 3 6 9
funcao(tibl[2])
#> numeros1 numeros2 numeros3 numeros4 numeros5 numeros6
#> 3 6 9 6 9 12
