goProfiles (version 1.34.0)

basicProfile: Builds basic functional profile

Description

Compute basic functional profile for a given list of genes/GO identifiers, a given ontology at a given level of the GO

Usage

basicProfile(genelist, idType = "Entrez", onto = "ANY", level = 2,orgPackage=NULL, anotPackage=NULL, 
	ord = TRUE, multilevels = NULL, empty.cats = TRUE, cat.names = TRUE, na.rm = TRUE)

Arguments

genelist

List of genes on which the Profile has to be based

idType

Type of identifiers for the genes. May be 'Entrez' (default), BiocProbes or GoTermsFrame (see details below).

onto

Ontology on which the profile has to be built

level

Level of the ontology at which the profile has to be built

orgPackage

Name of a Bioconductor's organism annotations package ('org.Xx-eg-db'). This field must be provided if the gene list passed to the function is either a character vector of 'Entrez' (NCBI) identifiers or a character vector of probe names

anotPackage

Name of Bioconductor's microarray annotations package. This field must be provided if the gene list passed to the function is a character vector of probe names

ord

Set to 'TRUE' if the profile has to appear ordered by the category names

multilevels

If it is not NULL it must be a vector of GO categories that defines the level at where the profile is built

empty.cats

Set to 'TRUE' if empty categories should appear in the profile

cat.names

Set to 'TRUE' if the profile has to contain the names of categories

na.rm

Set to 'TRUE' if NAs should be removed

Value

An object of class GOProfile (one or more data frames in a list named by the ontologies)

Details

The function admits three types of entries: Entrez ('Entrez'), Bioconductor probe set names ('BioCprobes') or a special type of data frames ('GOTermsFrames'). If the identifier type are 'BioCprobes' then an annotation package name must be provided too.
