I might suggest looking into the possibility of using SQLite, which is
cross platform and free (in fact, it's public domain rather than GNU
etc.).
You can then set up an Excel spreadsheet to populate itself from the
SQLite db. http://www.sqlite.org. It's already available on the Mac -
open a terminal window and type sqlite3, and you should enter the
environment. Check the website for details of how to set up the
database connections.
Good luck -

Here is another option:
On rcom.univie.ac.at
We have ROOo, R for OpenOffice.
This is an addin for OpenOffice, and it works on OSX. It allows to
transfer matrices and dataframes
from R to OO. In OO, you then could save your data as Excel files.
It cannot be done directly from R, you need to start OO and perhaps
write some macros in OO.

Ivan,
A quick heads up.
I had a brief offlist exchange with Prof. Ripley, during which he
noted two things:
1. His MS Office 2008 installation on OSX does not have an ODBC
driver. So it would seem that it is not available from MS, which
would make sense with Actual Tech selling one.
2. The Actual Tech driver is read only, meaning that you can read
from an Excel file, but not write to one. This is also noted in
Section 7 of vignette("RODBC"). After going back to the Actual
Tech web site on the page I listed, they do mention this in the
text on the page, where it indicates the for Excel, only 'select'
statements are supported and for Access, only 'select' and 'join'
statements. 'insert' and 'update' queries are not supported.
Thus, the Actual Tech product and indeed, [R]ODBC will in fact, not
do any of what you want here.

Thanks a lot Marc for your detailed answer.
With this information, I'll find what I can do with my data.
Thanks again to all of you
Have a nice weekend

Ivan,
If you wanted to evaluate the ODBC route, the Actual Tech driver
is available here:
http://www.actualtech.com/product_access.php
It is $29.95 U.S.
In hindsight, as I don't use MS Office, I don't know if their OSX
offering in fact has an ODBC driver included. Someone else here
may know that.
FWIW, I use Actual's Oracle ODBC driver and have been pleased
with it.
I should note that WriteXLS does not facilitate appending new
worksheets to an existing file or new data to an existing
worksheet. It creates a new .XLS file when used, overwriting an
existing file of the same if it already exists. The intent is to
provide the means to easily dump one or more data frames to an
Excel file as a means to make data from R portable to others
where an .XLS file makes sense as the vehicle, as an alternative
to CSV files, etc. So the intent would be to have all of your
data frames created and then use WriteXLS() to export them at once.
I had this need when I was using Linux (to send data to clients
on Windows) and so needed to find the way to accomplish this when
Excel itself would not be available. Thus Perl was used, which
makes this common approach available on Linux, OSX and Windows.
Regards,
Marc

How am I supposed to do that?
Marc Schwarz advised me to use the package WriteXLS instead.
Thanks for your help already

Dear Mac users,
Up to now, I've run R on Windows and I have some problems
using my scripts on Mac OS X 10.6, R.app GUI 1.31 (5537
Leopard build 64-bit).
Here is the code I use to export a data.frame to an *.xls file:
xlsFile <- odbcConnectExcel("test.xls", readOnly=F)
sqlSave(xlsFile, test, tablename=test, rownames=F, addPK=T,
append=F)
odbcCloseAll()
However, the function odbcConnectExcel() doesn't work on Mac.
Have you installed the necessary ODBC drivers and registered
them?
Cheers,
Simon
Could you help me transposing this code?
I don't think some sample data would be necessary, but let me
know if you would like to.
Thanks in advance
Regards,
Ivan
