Thank you very much. It works very well. However, after this line
temp - sapply( temp , as.numeric )
the data becomes a series of numbers instead of a matrix. Is there any
way to keep it a matrix?
Thanks,

sorry, i had assumed readWorksheetFromFile would give you back a data
frame. all of the operations i recommended work on data.frame objects

# view what data types your file is being read in as
sapply( temp , class )
# convert all fields to character if they're factor variables.. but i don't

Hi,
Attached are two datasheet to be read.
