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

Dear all,
I am struggling with a problem which I have been reading on the forums about
and it did not seem to me that there is a precise answer to my question.
However, I still hope there is one.
I am working with http://timss.bc.edu/ PIRLS data and trying to conduct
multilevel analysis. There are different weights for each level of analysis
in the PIRLS dataset (e.g. there is a school weight, class weight, student
weight).
Is there a function in R which would let me use different weights for
different levels of my model?
If yes, which package contains it?
I would be very grateful for any help!
