Subsetting data frames without a loop
I KNOW this should be easy, but I'm stuck. My data frame consists of multiple observations from each of a number of stations, and what I would like to do is create another data frame that contains all the variables of the first, but only rows where a certain variable is at its maximum for the station. So, for example: > my.df stn obs v 1 1 1 0.26400396 2 2 1

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!

computational ontology to research questions, and statistical methods
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

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.

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

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 known protein complexes. Can anyone suggest a simple workflow

Strange behavior of is.na() on 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

About ability of "allShortestPaths" function in e1071 package
Hello. R's e1071 package has "allShortestPaths" function using Floyd's algorithm. It is very useful for road network analysis. I'll try to analyze facility allocation programs using this. I'd like to know how much nodes this function can deal with? And for larger nodes(for example million nodes), allShortestPaths employs graph partition algorithm? Regards.

How to apply XPath query on XML nodes separately?
Dear R experts, I try to extract certain child nodes from an XML document and construct a table in which the parent node names are the columns and the child id values, joined in a list, are the cell content. If I first apply an XPath query to extract all above parent nodes, then iterate over those nodes and again apply a XPath query to select their child nodes, I get *ALL* matching child nodes
