Hi folks,

Problem in reading Excel spreadsheets

(the text file, research_databaseI.xls, was download on Internet)

> odbcClose(data)
> mydata

The printout doesn't look like the content of Excel spreadsheet.  Many data
disappear.

I read ?RODBC and the pdf file started with "RShowDoc("RODBC",
package="RODBC").  I couldn't figure out the cause of problem.


Is "RODBC" not the way to read Excel spreadsheets on R?  TIA
