Read & name multiple excel sheets using RODBC
I'd like to be able to read multiple sheets from an excel workbook and use
the sheet name to name the resulting dataframe using RODBC. at the moment
i've figured out how to do it the long way (see below) but feel sure that
there is a speedier & possibly automatic way to do it in R. i've tried to
run a loop using sqlTables but it seemed to break the connection. unless

write.xls
Hello, All:
The "writeFindFn2xls" function in the "sos" package tries to
write an Excel file with 3 sheets ('PackageSum2', 'findFn', 'call').
Unfortunately, it is often unable to do this because of configuration
problems that are not easy to fix. I've found 3 contributed packages
that provide facilities to write Excel files with

RODBC: sqlSave leave primary key and other columns null
I have an existing table, and I am trying to use sqlSave to append
additional rows to this database. I omit the primary key, which is a
uniqueidentifier type (MS SQL), so that the database can populate that
field. However, I get the following error:

rownames=FALSE, colnames=FALSE )

RODBC sqlSave / append problem (windows XP, R 2.13.2)
Dear All,
Using RODBC I have read in a (429 x 11) dataframe from Access, and would
like to append two columns of transformed data (429 x 2) to the original
table (thereby making it a 429 x 13 table). I would ideally like this to
be the same name etc as the original table in Access.
I have used the following command:

RODBC to import/export xls files
Dear R users,
I've learned today about RODBC package in order to import xls file to
dataframes and export the dataframes to xls files.
However I have some problems. Please excuse me if these are basic but as
I said, I've just begun with this package.
Also this email is quite long, but everything is related, so I don't
think it would be better to split it. Moreover, there's a

problem with looping on sqlSave()
Dear R users,
I have a follow-up question on sqlSave().
Since most of the output from the tests I use are lists, I would like to
loop to export each element of the list and append it to the sheet.
Here is what I do:

RODBC sqlSave with DB2
I am running R version 2.8.1 on Windows XP OS.
This works fine. (Data.frame dta is created with records from the DB2

RODBC: problem saving a new table in an "Excel database"
Hi
I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows
XP Pro. I am having problems writing a new table to an (Excel) database
using sqlSave.
I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I
believe, uses the Microsoft Excel Driver DSN). Then I try and save a new

Writing .xlsx files
Dear all,
I have been looking for possibilities to read and write Excel 2007-files
in and from R.
The 'reading' part is ok through odbcConnectExcel2007 and sqlFetch(RODBC).
For 'writing' I thought of using sqlSave in the same package, but it
does not work (I think because this function starts from an existing
file). Is there a workaround for this, or are there other plausible

Updating a worksheet in Excel file using RODBC
Hello!
I have no problem reading Excel files (each worksheet in the file is a "table" which can be read - at least in my case).
What I would like to do is to read such a table, change it (just the contents, not the format) and write it back, and this I can not do. I am getting the following error messages (3 slightly different attempts):

RODBC connection to locked Excel2010 files
Hi,
I am trying to connect to an Excel2010 file while another user is entering
data. (Obviously it would be better to set up a SQL database, but this is
not an option at this point.). Typically we are not working on the same
sheets. However, if possible I like to read the most current excel file
into R.
RODBC works great as long as the other user has not open the file. I tried:

Con ambos tengo el mismo problema así que planteo uno de ellos, éste es:
