Examples

{
##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))
davidGeneCluster1

##Now we can invoke DAVIDCluster ancestor functions to inspect the report
##data of each cluster. For example, we can call summary to get a general
##idea, and then inspect the cluster with the higher Enrichment Score, to see
##which members belong to it, etc. or simply, returning the whole cluster as
##a list with EnrichmentScore and Members.
summary(davidGeneCluster1)
higherEnrichment<-which.max(enrichment(davidGeneCluster1))
clusterGenes<-members(davidGeneCluster1)[[higherEnrichment]]
wholeCluster<-cluster(davidGeneCluster1)[[higherEnrichment]]


##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")
untar(fileName)
davidTermCluster2<-DAVIDTermCluster(untar(fileName, list=TRUE))
davidTermCluster2

##Now we can invoke DAVIDCluster ancestor functions to inspect the report
##data of each cluster. For example, we can call summary to get a general
##idea, and then inspect the cluster with the higher Enrichment Score, to see
##which members belong to it, etc. Or simply returning the whole cluster as a
##list with EnrichmentScore and Members.
summary(davidTermCluster2)
higherEnrichment<-which.max(enrichment(davidTermCluster2))
clusterGenes<-members(davidTermCluster2)[[higherEnrichment]]
wholeCluster<-cluster(davidTermCluster2)[[higherEnrichment]]
