organismBM: Retrieve Biomart Marts and Datasets for an Organism

Description

This function returns either all available biomart connections for all available organisms for which biomart access is possible, or (when specified) returns all organism specific biomart connections.

Usage

organismBM(organism = NULL, update = FALSE)

Arguments

organism

a character string specifying the scientific name of a query organism. Default is organism = NULL. In this case all available biomart connections are returned.

update

a logical value specifying whether or not the local listMart.txt and listDatasets.txt files shall be updated by remote access to BioMart.

Details

This function collects all available biomart connections and returns a table storing the organism for which biomart connections are available as well as the corresponding mart and database.
