Package Survey

How I use the function as.svrepdesign without memory.size problems?

desenho_npc_JK <- as.svrepdesign(desenho_npc,type="JKn")

Error: cannot allocate vector of size 161.3 Mb

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.
