I don't know the answer to your question, but I avoid these problems by saving my data as csv and avoiding direct interaction with Excel files. Excel is NOT a database, even though it has supposed support through ODBC. I find this holds true regardless of the programming environment from which I try to access Excel.

Hi all, I am trying to read Excel file usingthe follwoing commnad library(RODBC) data=odbcConnectExcel(file.choose()) sqlTables(data) Bdat=sqlFetch(data, "test") odbcClose(data) head(Bdat) 1. The above script works if the Excel file is opened. If the excel file is not opened then I get the following message "External table is not in the expected format" and it stops. 2. Instead of "(file.choose())" I wanted to use the following command data <- read.table('G:/test.xlsx", header=T) But it did not work again. Warning message: In read.table("G:/test.xlsx", header = T) : incomplete final line found by readTableHeader on 'G:/test.xlsx' Did I miss something there? Your help is highly appreciated Val 	[[alternative HTML version deleted]]_____________________________________________
