you can set the sampleNames of an ExpressionSet object by
sampleNames(richard) <- ....
for example:
sampleNames(richard) <- cels

I am sorry, but I do not understand what you want to do or what the
problem may be.
Can you please give more details? What exactly is being put in one column?
Please also provide the output of "sessionInfo()"
to let us know which package versions you are using.

Best regards,
Joern
