[R] output

[Marc Schwartz]

Hi,

With the WriteXLS() function, from the package of the same name, if you specify '.xlsx' for the file name extension, the function will create an Excel 2007 compatible file, which can handle worksheets of up to 1,048,576 rows by 16,384 columns.

Thus:

  WriteXLS(dat, "test4.xlsx", row.names = FALSE)

That is all described in the help file for the function.

Regards,

Marc Schwartz
