I am assuming that this is for a cdf package for which you cannot just 
go to netaffx and download? If not, just do that.

If you cannot just get the CDF from netaffx, then the next question is 
for you to define 'easily'. ;-D

Hypothetically you could use the writeCdf() function in affxparser to 
write out a cdf, but you would first have to coerce the data into the 
expected format (basically a complex list structure). Doesn't sound like 
fun to me.

Best,

Jim
