[BioC] Help on read.SMD() and read.SMD2()

[Dongxiao Zhu]

Hi all,

Please forgive me if it has been posted and answered before.

I spent several hours trying to use read.SMD() or read.SMD2() in the
"marray" package to generate marrayRaw object, but failed. I downloaded
the raw cDNA data from SMD. Error message is:

Error in "[.data.frame"(dat, , info.id) : undefined columns selected

I have also tried several other SMD datasets, but had the same problem.
Can somebody help me out?

Many thanks.

Dongxiao
