The recommended way to make data available is to use the data()
construct.
If you want to avoid it, you can assign the data.frame to a variable
name (the name "data" isn't a good idea, because data() is already a
function) as you described above, e.g. put it in a file "zzz.R".

This is described exactly in the manual "Writing R Extensions" in
chapter 1, particularly see section 1.1.3.
