[R-SIG-Finance] Does anybody know how to connect to KDB from within R?

[Michael]

Cool!

I've seen the following files in that folder:

Index of /q/interfaces/r/w32

	Name	Last modified	Size	Description
	Parent Directory	 	 -
	R.dll	12-Feb-2009 18:58	2.7M
	c.o	12-Feb-2009 18:58	 23K
	k.h	12-Feb-2009 18:58	3.3K
	kdbplus.R	19-Feb-2009 03:21	420
	kdbplus.dll	12-Feb-2009 18:58	 66K
	kdbplus.o	11-Feb-2009 08:30	 14K


How do I install these files to my R-system?

Thanks!
