I need to sample randomly my dataset for 1000 times. The sample need to be
the 80%. I know how to do that, my problem is that not only I need the 80%,
but I also need the corresponding 20% each time. Is there any way to do
Alternatively, I was thinking to something like setdiff () function to
compare my 80% sample to the original dataset and obtain the corresponding
20%, unfortunately setdiff works just for vectors, do you know a similar
function for dataframes?
