R help - Jun 2002 - large survey data set

---------- Forwarded message ----------
Hello,


I am analyzing a weighted, stratified, clustered survey data set
with approximately 1 million observations and 50 variables.

I am new to R (I'm a Stata user), and so far
couldn't find any documentation on how to handle survey data. In
other words, is there a specific package to handle a combination of
weigths, clusters and strata. I am also struggling to
handle such a large data set. Any suggestions and/or references regarding
these two issues would be greatly appreciated.

I don't think there is such a package. Most of the R functions that handle
weights do variance weighting rather than probability weighting.

Data management isn't all that easy in R, but it's certainly
possible.  There are some good tips here:
http://cran.r-project.org/doc/contrib/usingR.pdf

You can also put the data in a database and access them with one of the
database interfaces available (RODBC, RMySQL, RPgSQL).

I'm not sure what you mean by "handle" weights, clusters, and
strata. I'm guessing you want to use the nlme package, but it really
depends on what questions you want to ask.

Best,
Andy Perrin
