Marc, Thanks! x.num <- as.numeric(readClipboard()) works perfect. Meanwhile, I have tried to use odbcConnectExcel from RODBC pack. It seems to work as well. I am able to read in the data, but I need to construct a sql table from the data, and use sqlFetch to retrieve and assign them to variable. More steps.
