visnetwork

问题 I plot a simple network using visNetwork but when I try to save it as png I get an empty image as a result. png("ex.png") require(visNetwork, quietly = TRUE) # minimal example nodes <- data.frame(id = 1:3) edges <- data.frame(from = c(1,2), to = c(1,3)) visNetwork(nodes, edges, width = "100%") dev.off() 回答1: You can save the network as html and then capture the content of that file: nodes <- data.frame(id = 1:3) edges <- data.frame(from = c(1,2), to = c(1,3)) library(visNetwork) plot<-

问题 In the following vis-network I have 2 groups of nodes. I have separated the 2 groups of nodes into left and right side by accessing the node positions after generating a layput_as_tree . Then using visEvents drew an ellipse around the node groups to show the separation more defined as 2 cell structures. I would like to control the arrangement of the node positions. For example, some nodes need to be on the boundary of the ellipse, some at very center and some scattered around. Wondering if

问题 Using R, I create some fake data about a group of people and their relationships to each other: #relationship data Data_I_Have <- data.frame( "Node_A" = c("John", "John", "John", "Peter", "Peter", "Peter", "Tim", "Kevin", "Adam", "Adam", "Xavier"), "Node_B" = c("Claude", "Peter", "Tim", "Tim", "Claude", "Henry", "Kevin", "Claude", "Tim", "Henry", "Claude"), " Place_Where_They_Met" = c("Chicago", "Boston", "Seattle", "Boston", "Paris", "Paris", "Chicago", "London", "Chicago", "London", "Paris"
