I have tuples of data in rows of a data.frame, each column is a variable
for the 'items' (one per row).
One of the variables is the 'size' of the item (row).
I would like to cut my data.frame into groups such that each group has
the same *total size*. So, assuming that we order by size, some groups
should have several small items while other groups have a few large
items. All the groups should have approximately the same total size.
I have tried various combinations of cut, quantile, and ecdf, and I just
can't work out how to do this!
Any help is greatly appreciated!
All the best,
