Network visualization full options setter. Using this function, you can pass all network options you want, respecting the library format rather than use visNodes, visEdges, visGroups.... There is no control, so it's at your own risk !
visSetOptions(graph, options = NULL)
See online documentation https://datastorm-open.github.io/visNetwork/
nodes <- data.frame(id = 1:3)
edges <- data.frame(from = c(1,2), to = c(1,3))
# using visNetwork functions
visNetwork(nodes, edges) %>% visNodes(shape = "square", color = "red") %>%
visEdges(arrows = "to")
# directly use visSetOptions
visNetwork(nodes, edges) %>%
visSetOptions(options = list(nodes = list(shape = "square", color = "red"),
edges = list(arrows = "to")))
