I found and loaded the "survey" package.  ?rake and ?postStratify seem
promising.  Are there other packages/procedures I've missed?  Are there
online references that an R newbie could use to feel comfortable
applying these procedures to a survey?  How about a reference discussing
the details of designing a "post survey survey" to generate additional
weights?

 

 

Thanks in advance,

Subject: Survey questions



First the R question.  I have the results of a rather large survey
(thousands of forms, each with dozens of questions) with some existing
weights and expansion factors.  I wish to add additional weighting
factors, based on new information that elements of certain variables
should appear in certain proportions.  Where should I look in R to
develop what is essentially an N-dimensional balancing process.  I'd
like to develop new weighting factors, without disturbing the existing
weightings/expansion.  





Now the statistics question.  Is this appropriate?  Where can I find a
nearly entry level discussion of the statistical ramifications of this?
Is it possible (proper) to re-survey a population to obtain new weights
(for previously un-weighted responses) for an original survey?  



  



Thanks in advance,
