attributeSummary {biomaRt} | R Documentation |
Attributes in BioMart databases are grouped together in attribute groups and attribute groups can in their turn form a higher collection in an attribute category. The attributeSummary function gives a summary of the attribute categories and groups present in the BioMart. These group and category names can be used to display only a subset of the available attributes in the listAttributes function.
