I have the nodes and edges datasets below and I would like to know if I could run the simple path function for more than one names at once instead of one at a time.
name<-c("Robert Zero", "Amy Adams", "Barry Beane", "Henry Handler", "Julie Jones",
"Charlie Cheese", "Karen Klein", "Lolly Landswright", "Imogene Isler", "David Dufresne",
"Frank Flaherty", "Egbert English", "George Graham", "Molly McKee", "Norman Needle",
"Oscar Oliver", "Peter Platteville", "Quincy Quebec", "Roger Rabbit", "Steve Sweet",
"Tom Thompson", "Victor Valentino", "Ulrich Uxbridge" )
label<-c("Robert Zero", "Amy Adams", "Barry Beane", "Henry Handler", "Julie Jones",
"Charlie Cheese", "Karen Klein", "Lolly Landswright", "Imogene Isler", "David Dufresne",
"Frank Flaherty", "Egbert English", "George Graham", "Molly McKee", "Norman Needle",
"Oscar Oliver", "Peter Platteville", "Quincy Quebec", "Roger Rabbit", "Steve Sweet",
"Tom Thompson", "Victor Valentino", "Ulrich Uxbridge" )
nodes<-data.frame(name,label)
from<-c("Robert Zero", "Amy Adams", "Barry Beane", "Barry Beane", "Barry Beane",
"Julie Jones", "Karen Klein", "Imogene Isler", "David Dufresne", "Frank Flaherty",
"Egbert English", "George Graham", "Molly McKee", "Molly McKee", "Amy Adams",
"Peter Platteville", "Amy Adams", "Roger Rabbit", "Julie Jones", "Robert Zero",
"Steve Sweet", "Tom Thompson", "Steve Sweet", "Ulrich Uxbridge", "Henry Handler",
"Barry Beane", "Barry Beane", "Charlie Cheese", "Barry Beane", "Victor Valentino",
"Tom Thompson" )
to<-c( "Amy Adams", "Barry Beane", "Henry Handler", "Julie Jones", "Charlie Cheese",
"Karen Klein", "Lolly Landswright", "Robert Zero", "Frank Flaherty", "Robert Zero",
"George Graham", "Robert Zero", "Norman Needle", "Julie Jones", "Oscar Oliver",
"Robert Zero", "Quincy Quebec", "Robert Zero", "Molly McKee", "Steve Sweet",
"Tom Thompson", "Victor Valentino", "Ulrich Uxbridge", "Barry Beane", "Robert Zero",
"Imogene Isler", "Peter Platteville", "Robert Zero", "Roger Rabbit", "Robert Zero",
"Roger Rabbit" )
edges<-data.frame(from,to)
#Combine them in order to create the graph object
library(igraph)
library(dplyr)
gph <- graph_from_data_frame(edges, directed=TRUE, vertices=nodes)
#Create the simple paths asp
asp <- all_simple_paths(gph, "Steve Sweet", "Robert Zero")
asp2 <- all_simple_paths(gph, "Amy Adamas", "Robert Zero")
Instead I would like something like:
asp <- all_simple_paths(gph, c("Steve Sweet","Amy Adams"), "Robert Zero")
which would give me the 12 paths instantly
Try sapply with all_simple_paths
asp <- unlist(
sapply(
c("Steve Sweet", "Amy Adams"),
all_simple_paths,
graph = gph,
to = "Robert Zero"
),
recursive = FALSE
)
which gives
> asp
