[R] another very simple loop question

I have a dataset with 4 years of students, and normally I want to
estimate things using each individual year, so I have a for loop as

for (i in 1:4){}

However, the only way I know how to calculate estimates using all four
years of data is to put the estimations outside of the loop.  Is there
anyway to make a for loop that uses all four years at once, then uses
each individual year?
