[R] using postgresql with R/RODBC

[Larry White]

There's only one CRAN RODBC entry under Packages (version 1.1.3). 
That's the one I used.  The  'Depends' line seems to indicate that it
should work with any version of R > 1.9.

In any case, after I received the reply I went back to CRAN and took a
different path (under windows binaries) and located an earlier version
of RODBC (1.1.2).  When I tried that one I get this error:

Error in library(RODBC) : 'RODBC' is not a valid package -- installed < 2.0.0?

Aside from the Depends entry and the runtime error message there
doesn't seem to be any thing to indicate which version is appropriate
for R 2.0.1.

BTW, I'm on win 2000, if that would make a difference.
