How to split data into training/testing sets using sample function

Question

I\'ve just started using R and I\'m not sure how to incorporate my dataset with the following sample code:

sample(x, size, replace = FALSE, prob = NULL)
         


        

Answer 1

scorecard package has a useful function for that, where you can specify the ratio and seed

library(scorecard)

dt_list <- split_df(mtcars, ratio = 0.75, seed = 66)

The test and train data are stored in a list and can be accessed by calling dt_list$train and dt_list$test
