dependent variable. our goal is to formalize this link through a
computational ontology, which would standardize and hopefully
facilitate package and library development for R.
we have started some parallel efforts regarding both our requirements
for this ontology as well a search for existing ontologies. So far we
couldn't find any existing ontology, which seems odd given the
widespread application such an ontology has
Question for the list members: Is anybody aware of any existing
ontologies computational focusing on this topic?

OWL ontologies in R?
Are there any R packages to import and use Web Ontology Language (OWL)
ontologies (represented in OWL/RDF or other form)?

[R-1.4.0] minimum spanning tree of large ontology
Dear all,
I have an ontology which I would like to load in R to then compute the
minimum distance between elements.
Since this ontology is not only DAG, the problem is non trivial and
therefore decided to use R with the powerful e1071
library (allShortestPaths) to do that. That method requires to provide a
distance matrix between the
various objects. My ontology contains 32768 objects and

gene ontology association
Hello! I don't know if there is some R-package able
to associate ontology to a long list of GeneBank Name (a txt-tab file or
an XML file), i.e.
I would as output a formatted file with 4 columns (1:GeneBank Name
2,3,4:ontology).
I know that I have to perform a mapping of genes, I got a look on
AnnBuilder pkg,
but I 've not idea from where to start.
Some suggestion? Thanks in advance!

GO & Protein Complex Analysis for Homo sapiens
Dear All,
I need to fetch GO ontologies for Homo sapiens with their mappings to
corresponding Uniprot identifiers. I would be using this information to
compare result from a clustering algorithm with existing protein complexes.
This would be a test to check how the clustering algorithm accurately
captures GO terms with respect to the kno...

Strange behavior of is.na() on lists

I have observed that is.na() behaves strange on some lists. Here is a

+ print(is.na(a))
[1] TRUE

how to map microarray probe to gene, homology
Hi:
I have clustered microarray gene expression data and trying to map between
microarray probe, gene, pathway, gene ontology, and homology for a set of
(affy) microarray probes. Is there any package in R which facilitates this?
I am looking at bioconductor, but till now could not find a solution. A
link to some worked example would be appreciated.
Thanks and regards.

I'd suggest at some point to look into separate stream solution for
metadata, perhaps M3F [1].

Question to use R plot GO pie chart
Hi,
I have a list of IPI gene IDs. I want to find out whether there is a
package which can map the gene ontology to these IPIs, and plot the
pie chart to demonstrate the molecular function distributions.
The input is like the following gene IPI IDs:
IPI:IPI00008860.1|SWISS-PROT:Q9BXJ4-1|TREMBL:Q542Y2|ENSEMBL:ENSP00000231338;EN

Help with 'annotation' in GOHyperGParamsClass
Dear cateGOry experts,
hyperGTest documentation states that YEAST cannot be used as 'annotation'
when evaluating gene ontology representation status for a given set of
'geneIds'.
Because I am using a custom print I believe I need to create my own data
package to use as the annotation file for 'annotation'. Can someone please
describe how to make a data package that will

New package: codebook
...y will be.
Critiques, bug reports and enhancement requests are welcome as GitHub
issues. I'm a social scientist and tested this mostly on survey data. I'm
sure that shows in some design decisions. I'd be happy to find
collaborators who can e.g. fill in my knowledge gaps on metadata and
ontologies.

Project: Learning To Rank
Hello everyone,
I am Abhiroop, 3rd year engineering student from BITS Pilani, India. I was
going through the idea list of Xapian Search Engine Library and the idea
Learning to Rank interested me.
I am not very well conversant with C++. However I have done a lot of
development work in Java and Python. And i have done a project in C# too.
Currently I am working on 2 projects:
