our group at Duke is currently attempting to connect two data sets fed through a web-based system, one containing research questions (i.e., variables positioned with certain roles) and a database of statistical methods. this connection is done informally in a number of R packages and related software such as Rcmdr, R4calc, and Rkward where a variable of a certain type is matched to a certain

Dear Jean-Marc: Would you please send Thierry an ontology mapping table specification for speex according to the format he links to at the end of his message below? Thank you.

Are there any R packages to import and use Web Ontology Language (OWL) ontologies (represented in OWL/RDF or other form)? Thanks, -s [[alternative HTML version deleted]]

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

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!

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 known protein complexes. Can anyone suggest a simple workflow

Hello R-users, I have observed that is.na() behaves strange on some lists. Here is a simple example: > a = list(list('asd')) > a [[1]] [[1]][[1]] [1] "asd" > for(i in 1:5) + print(is.na(a)) [1] TRUE [1] FALSE [1] TRUE [1] TRUE [1] TRUE > > for(i in 1:10) + print(as.integer(is.na(a))) [1] 0 [1] 10 [1] 1 [1] 0 [1] 140897024 [1] 134567568 [1] 1 [1] 1953720684

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.

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

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

Dear R users, codebook (v. 0.5.8) was just released on CRAN. https://CRAN.R-project.org/package=codebook It uses the metadata/attributes that some other packages add (item labels, value labels, labelled missings) to automatically generate a codebook that is both human- and machine-readable. It combines metadata about the variables with data summaries. Many people will import this kind of

...fication or SVM or neural network approach,checking their success for various queries and then choosing the best. Both the above mentioned projects are being done in Java. In the second project I am ranking among the links which various users using have visited. Principally i am planning to use an ontological approach by classifying the links into various class labels and then ranking within the individual class using AKTiveRank Algorithm . I feel I can contribute to the project however most of the codes that I have written are in Java or Python. Is it essential to use C++ to contribute to this project...
