The following works for me under WinXP Pro to create "myframe" as a data frame:

library(RODBC)
z <- odbcConnectExcel("c:/myfolder/mydata.xls")
myframe <- sqlFetch(z, "Sheet1")
close(z)

Are you indicating the name of the worksheet you want within the *.xls file? I suspect there could be additional issues on a non-Windows OS that I don't know about.

hope this helps,

I gather from reading the back-issues of r-help that it should be
possible (modulo a number of caveats) to read an excel (yuck!) file
into R using RODBC.  I have obtained and installed ODBC and the RODBC
package, but cannot for the life of me figure out how to go about
it.  Can anyone give me a simple recipe?

I have an excel file on cdrom, say:

        /mnt/cdrom/melvin.xls

I have started R and loaded the RODBC package.  I want to create
a data frame ``melvin'' by reading in /mnt/cdrom/melvin.xls.
What (in monosyllables --- step by step) do I do next?
