Hi , I am using Bioconductor/R and "inSilicoMerging" package. I got an error message:

INSILICOMERGING: Run with no additional merging technique... Error in (function (classes, fdef, mtable): unable to find an inherited method for function ‘annotation’ for signature ‘"character"

Please tell me what does this message means?

Tnx

My steps:

(1) download 

E-GEOD-52763 (E-GEOD-52763.raw.1.zip)  and 

E_GEOD-45006 (E-GEOD-45006.raw.1.zip

 (2) #code

library(affy)

library(annaffy)

ReadCell = ReadAffy()

Norm.data = rma(ReadCell)

(3) # code:

>eset1<-Norm.data

>eset2<-Norm.data

(4) # code:

library(inSilicoMerging)

>esets= list(eset1,eset2)

> eset_FRMA = merge(esets)

INSILICOMERGING: Run with no additional merging technique...

Error in (function (classes, fdef, mtable)  : 

  unable to find an inherited method for function ‘annotation’ for signature ‘"character"’

same error message:

>eset_BMC = merge(esets, method="BMC")
