I am trying to do preprocessing on xys files and have used the
pdInfoBuilder package to successfully build the annotation files,
everything works until rma(), if I skip it I also get the results using
ACME. But I would like to know why rma() didnt work with xys files.


class(xys)
[1] "TilingFeatureSet"
attr(,"package")
[1] "oligoClasses"

rma(xys)
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function 'rma' for signature
'"TilingFeatureSet"'

is this happening because the object is not of any of the "ExonFeatureSet",
"ExpressionFeatureSet", "GeneFeatureSet" or "SnpCnvFeatureSet".

I do see elsewhere people got it to work on XYS files
