Perhaps give the list one question at a time?

Here's a start for one of the questions, selected (almost) at random.
Give 80% of people a score of 1 on a x1, and 20% of people zero.

tempVar <- runif(1000)
x1 <- ifelse(tempVar < 0.8, 1, 0)

Tell us how far you've got.  Do you need to know about write.table()
for the saving the files, or is the problem with splitting a large
file, or generating the 1000 names ...
