Hello,
       I want to import a .cel file into R.  Under the Windows platform, i used the command "read.celfile" in the package "affyio" and successfully imported the data. However, when i turned to used R in Ubuntu and repeated the same steps, there was an error:

  "read.celfile("/home/bmi01/P1/1.CEL") :
  Is /home/bmi01/P1/1.CEL really a CEL file? tried reading as text, gzipped text, binary and gzipped binary
  Calls: read.celfile -> .Call"

 What is the problem?
