| getPathOnly {ggenealogy} | R Documentation |
Determine the path between two varieties
Description
Determines the shortest path between the two inputted vertices, and takes into account whether or not the graph is directed. If there is a path, the list of vertices of the path will be returned. If there is not a path, a list of character(0) will be returned. Note: For a directed graph, the direction matters. However, this function will check both directions and return the path if it exists.
Usage
getPathOnly(v1, v2, ig, geneal, silent = FALSE, isDirected = FALSE)
Arguments
v1 |
the label of the first vertex of interest (in character string format) |
v2 |
the label of the second vertex of interest (in character string format) |
ig |
the graph representation of the data genealogy (in igraph format) |
geneal |
the full genealogy (in data frame format) |
silent |
whether or not to print output (defaults to false) |
isDirected |
whether or not the graph is directed (defaults to false) |
