Pass a function input as column name to data.frame function

February 4, 2023

I have a function taking a character input. Within the function, I want to use the data.frame() function. Within the data.frame() function, one column name should be the function’s character input.

I tried it like this and it didn’t work:

frame_create <- function(data, character_input){

…
some_vector <- c(1:50)

temp_frame <- data.frame(character_input = some_vector, …)

return(temp_frame)

}

>Solution :

Either use, names to assign or with setNames as = wouldn’t allow evaluation on the lhs of =. In package functions i.e tibble or lst, it can be created with := and !!

frame_create <- function(data, character_input){
    some_vector <- 1:50
    temp_frame <- data.frame(some_vector)
    names(temp_frame) <- character_input
    return(temp_frame)
}
