Request help writing a function
...columns there is a single numeric code, 1, 2 or 3 or an NA.
3) My goal is to determine the percent of time each person used a 2 code. So if a person across these columns had say 8 numerical entries and if 4 of these were the number 2, the answer for that person would be 50%.
Best regards,

A file manipulation question
...ue in the contract field would be the highest value recorded for a single ID. As you can see above, the number of IDs varies irregularly. Given the above, the new file would look like the following:

Getting tripped up on NAs in trying to create new variable
.... For example,
the following syntax throws NA for row two instead of the hope for "0".
test <- ifelse(is.na(df$a) & is.na(df$b), NA,
ifelse((!is.na(df$a) | !is.na(df$b)) & ((df$a ==3 | df$b == 3)), 1, 0))
> test
NA NA 1 1 0 1
Any help much appreciated.

Would like to apply a weight variable to the summary function in Hmisc
...package, functions describe and summarize can explicitly take a
weight variable.
My question is can a weight variable be applied when using 'summary'?
For example, using...summary(var1 ~ var2) I would like to weight the data
by var 3 (same length).
Is this possible?
Thanks a lot.

Recoding a multiple response question into a series of 1, 0 variables

I know how to do this using brute force (by writing bunch of ifelse statements), but given I have quite a lot of data in the above format, I was hoping a function would streamline this--I have tried to create a function for this, but my efforts to date have turned up junk.
