tables=TRUE does return a list of tables with no error. The problem

would send you the database, but it is for a military base and I don't

for all of the help.

Then you'll need to get mdb-tools to work outside of R on your Mac
before proceeding. Don't send any real database; only send a fake test
database that fails.

This is what I get when I try the above code
Error in type.convert(data[[i]], as.is = as.is[i], dec = dec,
na.strings = character(0L)) :
invalid multibyte string at '<ff><ff><fa><ff>'
If you can e-mail me a relatively small mdb file that fails for you I'll
debug. Also try specifying tables=TRUE to mdb.get to see if it can return
the list of tables in the database without an error.

Stephen -
You can modify your path on the fly with Sys.setenv:
Sys.setenv(PATH=paste(Sys.getenv('PATH'),'/sw/bin',sep=':'))
should make executables installed in /sw/bin available to R.

Frank,
I have tried to use this package, but because I am using fink to
install packages the mdbtools binary they are not accessible by the
function from within R. I checked this by just trying to call it with
the system function and R returned /bin/sh not found. I can access
the binary from the terminal, so the /sw/bin directory where mdbtools
is located is in my PATH- at least at a terminal.
thanks for the help,

The R Hmisc package interfaces these tools - see its mdb.get function.

thanks,
I think that on Linux and OSX, from an open source perspective, the
only
option is to use MDB Tools, though I have seen mixed reports of
success,
including some threads in the R-Help archives. It also appears that
there
has been no development on the package for about 5 years, as the
current
version (0.6pre1) dates from 2004. That may suggest limited, if any,
compatibility with recent versions of Access file formats.
You can download the source tarball here:
http://sourceforge.net/projects/mdbtools/
For OSX, it is available via MacPorts:
http://trac.macports.org/browser/trunk/dports/databases/mdbtools/Portfile
and for major Linux distributions, there are typically pre-compiled
binaries available via the standard repos and installation tools (eg.
yum
and apt-get).
There was also some work by the OO.org folks a while back to embed
MDB
Tools in OpenOffice, but I am not aware of the current state of the
project
or if it is even active any longer.
There is a commercial option from Actual Technologies:
http://www.actualtechnologies.com/product_access.php
which appears to provide an ODBC driver for Access on OSX. The page
focuses on the use of either Excel or FileMaker Pro with the driver.
However, you may be able to get it to work with RODBC.
I use Actual's ODBC driver for Oracle on OSX via RODBC, since Oracle
has
not seen fit to provide a free one as they do for Linux and have been
very
pleased. It was easy to install and configure, so take that for what
it's
worth.
