Select only numeric columns from dataframes in a list : RSTUDIO

I have this list of dataframes as follows :

library(carData)

library(datasets)

l = list(Salaries,iris)

I only want to select the numeric columns in this list of datasets. Already tried lapply with the function select_if(is.numeric) but it did not work with me.

Would appreciate the help. Thanks.

>Solution :

We can use select with where in the newer version of dplyr – loop over the list with map and select the columns of the data.frames

library(purrr)
library(dplyr)
map(l, ~ .x %>%
    select(where(is.numeric)))
