There is currently no easy way to affect the amount of memory that this
uses, unless you can divide the data into pieces -- for example, use only
some variables, or create separate design objects for strata.
The surveyNG package, which can handle very large designs, does not yet do
replicate-weight analyses.
One question is how big the design actually is.
161.3Mb looks like a vector of length 21 million
If this is the number of observations in the study then you need a
larger computer. If it is the total number of replicate weights then you
may just be able to increase the memory limit for R on your computer
using the memory.size() function, as the warning method suggests.
