I have a data frame that I am extracting some records from and noticed
the following issue
I originally used tmp - subset(dd, dd$EVYEAR==2012 dd$EVMONTH=='02')
and noticed that I wasn't ending up with all of the records I should
have; however, when I used
tmp - dd[dd$EVYEAR==2012
don't
need the dd$ in the arguments to subset().
But those don't explain your result given the information provided.
Please provide more information.

Petr,
Thank you for you assistance. Particularly this last bit. It really
helped me understand exactly how your solution worked and why I was
confused by rapply processing rows. It was apply that could process
rows (and/or columns) of a matrix,

Bind result with original data
survey.results - cbind(survey.results, result)
And voila, you shall have reqiured values.

Karen,
Thank you for your reply. That approach makes the code for determining
preference much clearer. Unfortunately, it appears I am still needing
to use a for loop to process each row.

I am having trouble understanding how to use sapply (or similar
functions) with a user defined function with multiple parameters.

retVal = 1
} else if (x ==2) {

I needed to compute a complicated cross tabulation to show weighted means

I have cobbled together the following logic. It works but is very

this kind of thing, but have been unable to find/understand one. Any

I need to regress data like the example below. The data points
