[R] "survey" package -- doesn't appear to match svy

[Anthony Damico]

could you provide a minimal reproducible example?  perhaps use ?dput.


in general the survey package matches all other languages
http://journal.r-project.org/archive/2009-2/RJournal_2009-2_Damico.pdf


here's an example of a minimal reproducible example that does match
http://www.ats.ucla.edu/stat/stata/faq/svy_stata_subpop.htm


library(foreign)
library(survey)
x <- read.dta( "
http://www.ats.ucla.edu/stat/stata/seminars/svy_stata_intro/strsrs.dta" )
y <- svydesign( ~ 1 , strat = ~strat , data = x , weights = ~ pw , fpc =
~fpc )
svytable( ~ yr_rnd , y )
z <- subset( y , yr_rnd == 1 )
svymean( ~ ell , z )



there are lots of examples of R matching official published statistics
(often computed with stata) here--
