topGO: Table of Top GO Terms or Top KEGG Pathways

Description

Extract top GO terms from goana output or top KEGG pathways from kegga output.

Usage

topGO(results, ontology = c("BP", "CC", "MF"), sort = NULL, number = 20L,  truncate.term = NULL)
topKEGG(results, sort = NULL, number = 20L, truncate.path = NULL)

Arguments

results

data frame produced by goana or kegga.

ontology

character vector of ontologies to be included in output. Elements should be one or more of "BP", "CC" or "MF".

sort

character vector of names of gene lists for which results are required. Should be one or more of the column names of results. Defaults to all gene lists.

number

maximum number of top GO terms or top KEGG pathways to list. For all terms or all pathways, set number=Inf.

truncate.term

truncate the name of the GO term at this number of characters.

truncate.path

truncate the name of the KEGG pathway at this number of characters.

Value

Same as results but with rows subsetted by Ontology and sorted by p-value.

Details

topGO organizes the output from goana into top-tables of the most significant GO terms. topKEGG similarly extracts the most significant KEGG pathways from kegga output. In either case, rows are sorted by the minimum p-value of any of the result columns specified by sort.
