get_parents

Retrieves the parent nodes of a given cell state in a state graph.

get_parents(state_graph, cell_state)

Arguments

• state_graph
  igraph
  An igraph object representing the state graph.

• cell_state
  character
  The specific cell state for which to find parent nodes.

Value

A character vector of parent node names. If there are no parent nodes, an empty character vector is returned.

Details

A state's parents are the states with an edge pointing into it. get_all_parents() is the recursive counterpart of get_parents() — it walks all the way up the graph to return every upstream ancestor, rather than just the immediate parent(s).

Examples

# Assuming `state_graph` is a pre-defined igraph object and `cell_state` is a valid node in the graph
parents <- get_parents(state_graph, cell_state)
print(parents)
