I would recommend search the R-help list for ways of reading .xls
files in R.
You might also try the RSiteSearch function in R.

take a look of
?read.table function
which can be used to rad .xls file and make expression set.

Depending on your OS, there are numerous ways to import the data. You
can do one of the following, in order of simplicity:
1.) Save the .xls file as .csv and open using read.csv()
2.) If on Windows, access the data using the RODBC package
3.) Open the .xls file using Excel (or OpenOffice or StarOffice if on
*NIX), copy the data, and import using scan("clipboard"). To be truly
useful, this will require you to pass a list identifying the column
type
and probably wrap scan() in data.frame().
Best,
Jim

Hi!
I have Affimetrix data, but I don't have .CEL files, only a .xls.
How can I open this file with Bioconductor?
Thank you.
