R help - Sep 2011 - chippeakanno package: "getAllPeakSequence" problem

Hi all,

I am using the package ChIPpeakAnno, and I have a problem with the function
getAllPeakSequence. This is related to object oriented programming I think,
I have the following message:
> peaksWithSequences <- getAllPeakSequence(peakList, upstream = 100,
> downstream = 100, genome = Hsapiens)
Error in validObject(.Object) : 
  invalid class "GRanges" object: superclass "Sequence" not
defined in the
environment of the object's class


Is the error coming from my configuration or from the code? I do not know
many things about OOP in R.

Thanks.

We do not know, since we do not know what your objects "peakList" and 
"Hsapiens" are, hence we cannot reproduce anything here. The example 
works fine for me.

Moreover, please ask question related to BioConductor packages on the 
BioC mailing list.

Best,
Uwe Ligges

Hi Nico902

Please ask questions about this Bioconductor package on the Bioconductor 
mailing list.

http://bioconductor.org/help/mailing-list/

Likely your packages are not at a consistent version. Follow these 
instructions

http://bioconductor.org/install/#update-bioconductor-packages

to update your packages.

I haven't ever seen that package mentioned on r-help befor, so it is  
probably a BioC package. Bioconductor which has its own mailing list.  
There are a small number of persons who are bicultural with ordinary-R  
and BioC, but they generally suggest to posters to use the BioC list.  
(I don't know if it has a Nabble interface. I'm guessing it does not.)

Thanks Martin, it worked.

I will post on BioC next time.

Cheers.
