[BioC] matchprobe

[Wolfgang Huber]

Dear Qing,

The "datafile" arguments needs to be a character string with a filename, 
not a connection.

Do read the man page of the function makeProbePackage and its helper 
function getProbeDataAffy, where this and many other useful pieces of 
information can be found.

Best wishes
  Wolfgang
