And the command that produced this was...? I'm guessing you ran merge("esets") or something like that, instead of merge(esets), but I pretty much have to read your mind to know what you're actually doing.

Hi Devon,

I am using "inSilicoMerging" and getting an error message:

Error in (function (classes, fdef, mtable)  :  unable to find an inherited method for function ‘annotation’ for signature ‘"character"’

I Use R version 3.1.0 ; Bioconductor version 2.14; on Mac OS X 10.7.5

My steps:

(1) # From ArrayExpress I download 2 raw zip files: E-GEOD-52763 (E-GEOD-52763.raw.1.zip) and E_GEOD-45006 (E-GEOD-45006.raw.1.zip

 # code

library(affy)

library(annaffy)

ReadCell = ReadAffy()

Norm.data = rma(ReadCell)

eset1<-Norm.data

# code

eset2<-Norm.dat

 # 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"’

 

or any other gave me the same error message:

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

> eset_NULL = merge(esets, method=NULL, norm="FRMA", features = "GENE");

> eset_12 = merge(esets, method=NULL, norm="ORIGINAL");
