[BioC] ReadAffy can not find function read.AnnotatedDataFrame

[Georg Otto]

Hi,

I am having a problem using ReadAffy using the new AnnotatedDataFrame class:

targets<-new("AnnotatedDataFrame")
pData(targets)<-read.table("Targets.txt", header=TRUE, row.names=2)

Data<-ReadAffy(celfile.path =cel.path,
               filenames = sampleNames(targets),
               verbose=TRUE)

Error in AllButCelsForReadAffy(..., filenames = filenames, widget = widget,  : 
	could not find function "read.AnnotatedDataFrame"

I have the newest devel version of Biobase installed (see below)

RSiteSearch("read.AnnotatedDataFrame")

did not give me a result.

Any idea what is wrong here or where I can find the requested function?

Best,

Georg
