[BioC] Bioconductor 1..6.1: espresso problem.

[Johanne Duhaime]

Hello

I am a new user of Bioconductor. I just installed version 1.1 on R
version 1.6.1. This is done on widows 2000.
I want to reproduce section 3.3 "Expression measures" of the document
"Textual Description of affy". But I keep having the same error whatever
I tried.
Can you help me? Thank you in advance.


> ReadAffy()
AffyBatch object
size of arrays=640x640 features (16003 kb)
cdf=MG_U74A (12654 affyids)
number of samples=5
number of genes=12654
annotation=mgu74a

> eset <-
expresso(affybatch,normalize.method="qspline",bg.method="rma",summary.method="liwong")

Error in expresso(affybatch, normalize.method = "qspline", bg.method =
"rma",  :
        unused argument(s) (bg.method ...)
