[R] Importing data by odbcConnectExcel in 64 bit

I have probably an old question.

I have R.3.0.1 installed in 64 bit windows 7. The odbcConnectExcel in RODBC
library does not work. Tried odbcConnectExcel2007 still does not work.


Any ideas.

Thanks

[R] Importing data by odbcConnectExcel in 64 bit

Can't help you with the odbcConnectExcel, but I can suggest an alternative
... loadWorkbook() and readWorksheet() in the XLConnect package work on
Windows 7 64-bit.

library(XLConnect)
wb <- loadWorkbook("C:/Temp/Mydata.xlsx")
dat <- readWorksheet(wb, sheet="Sheet1")

[R] Importing data by odbcConnectExcel in 64 bit

Tena koe

Perhaps the help file will give you some ideas:

"odbcConnectAccess, odbcConnectDbase and odbcConnectExcel are convenience
wrappers to generate connection strings for those file types. The files given
can be relative to the R working directory or absolute paths (and it seems also
relative to the user's home directory). The file name can be omitted, which
will on Rgui bring up a dialog box to search for a file.

Note: they will only work with English-language 32-bit versions of the Microsoft
drivers, which may or may not be installed in other locales, and are not usable
from 64-bit R. The 2007 versions work with the drivers which are installed with
Office 2007/2010 and give access to formats such as '*.xlsx' and
'*.accdb'. These drivers are also available separately and there is a
64-bit version: see the package manual. (You must have the 32-bit drivers when
using 32-bit R and the 64-bit drivers when using 64-bit R: otherwise there will
be a cryptic message about a driver not being found. And the 64-bit drivers
cannot be installed alongside 32-bit Microsoft Office, and vice versa.

See the package manual for some of the peculiarities of the Excel drivers.
readOnly = TRUE may allow very limited changes (to insert and update
rows)."

HTH ....
