Subject: vlookup type function
Hi
I''m looking for an Excel Vlookup type function in R.
Example:
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!
