Dear Bioconductors,

I am just looking through one of the vignettes with the /oligo/ package 
(V1Overview.pdf).
I have downloaded the test data from the Affymetrix link and am 
following the commands in the pdf:

library(pd.hg.u95a)
library(oligo)
celfiles <- list.celfiles(getwd())
affyExpressionFS <- read.celfiles(celfiles)
 > class(affyExpressionFS)
[1] "ExpressionFeatureSet"
attr(,"package")
[1] "oligoClasses"

but then I get to:
 > pmSeq <- pmSequence(affyExpressionFS)
Warning message:
In .local(object, ...) :
   pmSequence.rda file is not available for this pdInfo pkg.

 > pmSeq
NULL

pmSequence.rda is available, in Rdata.zip in 
R\R-2.11.0\library\pd.hg.u95a\data.  Any ideas how I can get R to 
realise that it is available?

With thanks for your time,

Lavinia Gordon.
