I know there is a temptation to want to open files using excel, but you
should resist that temptation. Instead, read the limma user's guide,
particularly starting on page 17. You want to read those files in using
read.maimages, with source="genepix".
The limma package has all the functionality necessary to read in and
analyze your data, and the limma user's guide has numerous examples that
should help you understand how to proceed.
