Get Events Contained in an Upstream Event

Source: R/reactome_content.R
rba_reactome_pathways_events.Rd

Reactome events can contain other events; for example, a pathway can contain smaller pathways and reactions. This function recursively retrieves all events downstream of the supplied event, or one attribute of those events.

Usage

rba_reactome_pathways_events(event_id, attribute_name = NULL, ...)

Arguments

event_id

Character or Numeric: Reactome event's database ID (DbId) or Stable ID (StId).

attribute_name

Character: Optional event attribute to return instead of complete event records. See Reactome Data Schema: Event for available options.

...

rbioapi option(s). See rba_options's arguments manual for more information on available options.

Value

A list with information about the contained events. If attribute_name is supplied, one value for each contained event is returned. If the individual values cannot be identified reliably, the complete result is returned as a single value.

Details

Reactome defines events as the building blocks of biological processes. Events can be pathways or reaction-like events and are organized hierarchically. An event can be a child or parent of another event, each hierarchy begins with a top-level pathway, and an event can belong to more than one hierarchy.

When attribute_name is supplied, the function returns one value for each contained event whenever the individual values can be identified reliably. Empty values and line breaks within a value are preserved. Otherwise, the complete result is returned unchanged with a warning. When save_file is used, the saved file always contains the result exactly as supplied by Reactome.
