While testing ArrayExpress with E-GEOD-17215 I see
Error in rma(ae) :
VECTOR_ELT() can only be applied to a 'list', not a 'character'
being thrown by rma applied to the downloaded AffyBatch - shown below.
Not
sure whether this is a problem with the source data at ArrayExpress or
stupidity on my own part, but I can't find any sign of this specific
error
text in any relevant google results - suggestions appreciated. R2.9.2
