Filtering pmSequence based on probe target level for HTA 2.0 arrays

List members,

I am working with some Affymetrix HTA 2.0 arrays. I have installed the
draft annotation package described here:
http://grokbase.com/t/r/bioconductor/1428394w2d/bioc-draft-support-for-hta-
2-0-with-oligo

I am using the following commands from the oligo package to extract
intensity values and PM sequences via the oligo package. However, I am
running into a problem because the oligo::pmSequence function doesn't
allow me to specify a target probe type for these arrays. By default
oligo::pm() uses the "core" probes, whereas oligo::pmSequence only allows
me to use the "probeset" probes. In contrast, for the ST arrays, I am able
to do this.

affyExpressionFS <- read.celfiles(celFilePath)
pint = oligo::pm(affyExpressionFS, target="core")

pmSeq = oligo::pmSequence(affyExpressionFS, target="core")



Below is the error message I get.

Loading required package: pd.hta.2.0
Loading required package: RSQLite
Loading required package: DBI
Platform design info loaded.
Reading in : testInputData/HTA2.CEL.gz
Error in { : task 1 failed - "unused argument (target = "probeset")"

Below is my session info. Any help would be appreciated.
