R help - Mar 2012 - Get data from Access 2010 database

Hello,

I'm new to R and am trying to access data from a Microsoft Access 2010
database. I've read through the RODBC package vignette and seem to
understand the instructions of the commands but can't see to connect to the
database. I have installed the Access Database Engine from the Microsoft
website.  I get the following errors when I try to connect:
> channel <- odbcConnect("K:/UWRRDatabase_9Feb2012")
Warning messages:
1: In odbcDriverConnect("DSN=K:/UWRRDatabase_9Feb2012") :
  [RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver
Manager] Data source name not found and no default driver specified
2: In odbcDriverConnect("DSN=K:/UWRRDatabase_9Feb2012") :
  ODBC connection failed

I setting up a ODBC connection in ODBC data sources in the Administrative
Tools of Control panel and also through
C:\WINDOWS\SysWOW64\odbcad32.exe
but I must not be setting things up correctly.

Any advice or suggestions to solve this problem would be much appreciated. 

Thanks in Advance.

AFAIK you need to use the 32bit version of R for getting the data. Then you can
save it into a more versatile format and re-read it if you really need to run R
in 64 bit mode.
