Hi,
Try package 'data.table'. It has a concept of keys which allows you to do
exactly that.

Hi Matthew,
Unfortunately, the load of that library fails (it builds successfully).
I'm currently looking into why. Error output looks something similar to:
> library(data.table)
Error in .makeMessage(..., domain = domain, appendLF = appendLF) :
could not find function "packageVersion"
Error : .onAttach failed in 'attachNamespace'
Error: package/namespace load failed for 'data.table'
I googled around a bit and there is mention of a bug in packageVersion
but there was no solution that I found. Is this something that is easily
overcome?
Thanks,
Jesse
