Hello,
The link you've posted is to a page that does NOT have a dataset, it has
links to other pages. The proper way of posting a data example would be
# paste the output of this in a post
dput(head(yourdata, 20)) # or 30
Now, if I understand your question, function sample() does have a
weights argument, 'prob'. (Package base.) See
help("sample")
Hope this helps,
Rui Barradas
