I know there are various R packages for performing raking (i.e. calibration to external estimates, iterative proportional fitting, etc) to construct survey weights. I wanted to find a package that would automatically collapse cells if a cell count fell below a certain value. Is there a package out there with such a feature? Or if not raking exactly, a weighting package for a similar algorithm (e.g. GREG, entropy balancing) that would have such a feature for matchings to targets. Thank you.
Doing initial research, packages like "Ipfp: Multidimensional Iterative Proportional Fitting" didn't seems to have the feature I wanted.
