How to use kable inside sapply in R

Question

My goal is to tabulate multiple columns at the same time and I used the following:

sapply(iris[1:4], table)

Next I tried to use kable to format the output, but I keep getting an error:

sapply(iris[1:4], knitr::kable(table))
Error in seq_len(m) : argument must be coercible to non-negative integer

So I'd like to know if it is possible to use kable inside sapply.

Thank you.

Answer 1

Did you try using the map() function from the purrr package?

This function applies any function to each element of a list (here, you have a data frame so it will apply the function to each column)

Personnaly, I do:

map(iris[1:4], function(.x){

        .x %>% knitr::kable() 
        #You can include any styling options after
})
