Hi I am having the following Warning message with this code:

> Error in file(file, "r") : unable to open connection
In addition: Warning message:
cannot open file- reason 'No such file or directory' in: file(file, "r")

The files are present on a CD and USB key- I tried opening all the
files-then running the script but, it makes no difference.
Basically....
How do I ensure that R reads my files to perform functions- I have some
files on CD and other on my a USB key.

Also if I am using script that was already written, for new data - how do I
know which info. in the existing script should be updated?

Thanks
