Description

Different ways to build the different DAVIDWebService's object according to the signature in use.

Usage

  DAVIDGenes(object)

  ## S4 method for signature 'character'
DAVIDGenes(object)

  ## S4 method for signature 'data.frame'
DAVIDGenes(object)

  ## S4 method for signature 'DAVIDGenes'
initialize(.Object, fileName)

  as(object, Class, strict=TRUE,
  ext=possibleExtends(thisClass, Class))

  DAVIDFunctionalAnnotationChart(object)

  ## S4 method for signature 'character'
DAVIDFunctionalAnnotationChart(object)

  ## S4 method for signature 'data.frame'
DAVIDFunctionalAnnotationChart(object)

  ## S4 method for signature 'DAVIDFunctionalAnnotationChart'
initialize(.Object,
  fileName)

  as(object, Class, strict=TRUE,
  ext=possibleExtends(thisClass, Class))

  ## S4 method for signature 'DAVIDCluster'
initialize(.Object, fileName)

  ## S4 method for signature 'DAVIDGeneCluster'
initialize(.Object,
  fileName)

  DAVIDGeneCluster(object)

  ## S4 method for signature 'character'
DAVIDGeneCluster(object)

  ## S4 method for signature 'DAVIDTermCluster'
initialize(.Object,
  fileName)

  DAVIDTermCluster(object)

  ## S4 method for signature 'character'
DAVIDTermCluster(object)

  ## S4 method for signature 'DAVIDFunctionalAnnotationTable'
initialize(.Object,
  fileName)

  as(object, Class, strict=TRUE,
  ext=possibleExtends(thisClass, Class))

  DAVIDFunctionalAnnotationTable(object)

  ## S4 method for signature 'character'
DAVIDFunctionalAnnotationTable(object)

  ## S4 method for signature 'data.frame'
DAVIDFunctionalAnnotationTable(object)

  ## S4 method for signature 'DAVIDGODag'
initialize(.Object,funChart,type=c("BP","MF","CC"),pvalueCutoff=0.1,removeUnattached=FALSE,...)

  DAVIDGODag(funChart, ...)

  ## S4 method for signature 'DAVIDFunctionalAnnotationChart'
DAVIDGODag(funChart,
  ...)

Arguments

object	could be a character with the file name of the .tab report or data.frame already loaded.
fileName	character with the file name of the .tab report to load.
.Object	character to use in new function call. Possible values are: "DAVIDGenes", "DAVIDFunctionalAnnotationChart" or "DAVIDCluster".
Class	character to use in the as function call. Possible values are: "DAVIDGenes" and "DAVIDFunctionalAnnotationChart".
strict,ext	see as function.
funChart	DAVIDFunctionalAnnotationChart object.
type	character to indicate Gene Ontology main category: "BP", "MF" or "CC".
pvalueCutoff	numeric >0 <=1 to indicate the p-value to use as the threshold for enrichment. Default value is 0.1
removeUnattached	Should unattached nodes be removed from GO DAG? Default value is FALSE.
...	Additional parameters for lower level constructors (initialize).

Value

a DAVIDWebService object according to function call:

DAVIDGenes	object with genes description related data.
DAVIDFunctionalAnnotationChart	object with the respective report.
DAVIDFunctionalAnnotationTable	object with the respective report.
DAVIDCluster	Not possible to invoke as it is a Virtual class.
DAVIDGeneCluster	object with the respective report.
DAVIDTermCluster	object with the respective report.
DAVIDGODag	derived GOstats GO Direct Acyclic Graph from DAVIDFunctionalAnnotationChart data.

Examples

{
##DAVIDGenes example:
##Load Show Gene List file report for the input demo file 1, using data
##function. Then, create a DAVIDGenes object using the loaded data.frame
##geneList1.
data(geneList1)
davidGenes1<-DAVIDGenes(geneList1)

##In addition, the user can use the file name of the downloaded file report.
##Here, we need to first uncompressed the report included in the package, in
##order to load it.
setwd(tempdir())
fileName<-system.file("files/geneListReport1.tab.tar.gz",
package="RDAVIDWebService")
untar(fileName)
davidGenes1<-DAVIDGenes(untar(fileName,list=TRUE))


##DAVIDFunctionalAnnotationChart example
##Load the Functional Annotation Chart file report for the input demo
##file 2, using data function. Then, create a DAVIDFunctionalAnnotationChart
## object using the loaded data.frame funChart2.
data(funChart2)
davidFunChart2<-DAVIDFunctionalAnnotationChart(funChart2)

##In addition, the user can use the file name of the downloaded file report.
##Here, we need to first uncompressed the report included in the package, in
##order to load it.
setwd(tempdir())
fileName<-system.file("files/functionalAnnotationChartReport2.tab.tar.gz",
package="RDAVIDWebService")
untar(fileName)
davidFunChart2<-DAVIDFunctionalAnnotationChart(untar(fileName, list=TRUE))


##DAVIDFunctionalAnnotationTable example
##Load the Functional Annotation Table file report for the input demo
##file 1, using data function. Then, create a DAVIDFunctionalAnnotationTable
##object using the loaded data.frame annotationTable1.
data(annotationTable1)
davidFunTable1<-DAVIDFunctionalAnnotationTable(annotationTable1)

##In addition, the user can use the file name of the downloaded file report.
##Here, we need to first uncompressed the report included in the package, in
##order to load it.
setwd(tempdir())
fileName<-system.file("files/annotationTableReport1.tab.tar.gz",
package="RDAVIDWebService")
untar(fileName)
davidFunTable1<-DAVIDFunctionalAnnotationTable(untar(fileName, list=TRUE))


##Example DAVIDGODag
##Load the Functional Annotation Chart file report for the input demo
##file 2, using data function. Then, create a DAVIDGODag object using
##Molecular Function main category of DAVIDFunctionalAnnotationChart object,
##obtained from the loaded data.frame funChart2. In addition, we have
##selected a threshold pvalue of 0.001 and removed unattached nodes, in case
##DAVID/GO.db database are not using the same version.
data(funChart2)
davidGODag<-DAVIDGODag(DAVIDFunctionalAnnotationChart(funChart2), type="MF",
pvalueCutoff=0.001, removeUnattached=TRUE)


##DAVIDGeneCluster example:
##Load the Gene Functional Classification Tool file report for the
##input demo list 1 file to create a DAVIDGeneCluster object.
setwd(tempdir())
fileName<-system.file("files/geneClusterReport1.tab.tar.gz",
package="RDAVIDWebService")
untar(fileName)
davidGeneCluster1<-DAVIDGeneCluster(untar(fileName, list=TRUE))


##DAVIDTermCluster example:
##Load the Gene Functional Classification Tool file report for the
##input demo file 2 to create a DAVIDGeneCluster object.
setwd(tempdir())
fileName<-system.file("files/termClusterReport2.tab.tar.gz",
package="RDAVIDWebService")
