I''m looking for an Excel Vlookup type function in R.

list <- c(1,2,3,4,5,6,7)
base <- c(2.2,3,5.2)

What I want is, for each number in base, the highest value in list,
which is equal to or less than the number in base

So the results would be:

base         list
2.2  ------> 2
3    ------> 3
5.2  ------>  5

Thanks for your help!
