well, I don't know anything about the limma package and I might be 
misunderstanding your apparently simple question

What I do for excel files is the following:
1. I save a copy of the file as .csv (comma separated values) in the 
working directory. This format allows you work perfectly with the file in 
2. open in R using:

 > read.csv("filename.csv")

Hope it helps
