Dear list

Can anyone enlighten me to the meaning of this error and how I might get round it?

> rma.ufr <- unifilter(data.rma, ...)

Error: UnitID <322394> not found.

An error has occured: Need to abort current process.

Error in .local(object, ...) : error in function ‘ExportData’


More details below

Thanks
John
