text_path: Display path (text form)

In rsemmed: An interface to the Semantic MEDLINE database

Description

Show a text display of a path and obtain output that can be used to explore predications along the path. (A predication is a SUBJECT–LINKING VERB–>OBJECT triple.)

Usage

text_path(graph, path, print = TRUE)

Arguments

graph	The SemMed graph
path	A vertex sequence (igraph.vs) (the path to display)
print	Print the path to screen?

Details

text_path invisibly returns a list of tbl's containing information on the predications on the path. Each list element is a tbl that corresponds to a (sequential) pair of nodes along the path. The tbl contains information on the subject and object node's name and semantic type as well as all predicates linking the subject and object.

Value

Invisibly returns a list of predications for each pair of nodes along the path.

Examples

data(g_mini)

node_cortisol <- find_nodes(g_mini, names = "Serum cortisol")
node_stress <- find_nodes(g_mini, names = "Chronic Stress")
paths <- find_paths(g_mini, from = node_cortisol, to = node_stress)
text_path(g_mini, paths[[1]][[1]])
result <- text_path(g_mini, paths[[1]][[1]], print = FALSE)
