问题 The following R script creates a visNetwork diagram as shown. How to manually change the straight edges to curved edges by giving a curved factor? One approach that I tried here using the roundness attribute with "smooth" label. However, not able to achieve it. library(visNetwork) nodes <- data.frame(id = 1:3,color = c(rep("blue",1), rep("red",1), rep("green",1))) edges <- data.frame(from = c(1,2,3), to = c(2,3,1)) nodes = data.frame(nodes, level = edges$from) visNetwork(nodes, edges, height

问题 The dataset "patients" is an eventlog of patients visiting a clinic and getting treatment. The script below gives a data frame with traces or sequence of activities in the eventlog, trace_id and absolute frequency of the cases following the particular trace. I wish to create a dynamic horizontal bar chart using ggplot2 or plotly such that the traces are represented like the snapshot attached with the absolute frequency in % at the top of the bar with axes labels. Thanks and please help!

问题 I would like to fix the positions of the nodes at (1,0), (0,1), (-1,0), (0,-1) and (0,0). However, it does not not work and my Java knowledge is zero (it seems, that here ist the question concering the Java code). Can anybody help? Here is an example: require(visNetwork, quietly = TRUE) nodes <- data.frame(id = 1:5) # x = c(1, 0, -1, 0, 0), # y = c(0, 1, 0, -1, 0)) edges <- data.frame(from = c(1,2), to = c(1,3)) visNetwork(nodes, edges, width = "100%") %>% visNodes(x = c(1, 0, -1, 0, 0), y =

问题 I'm exploring visNetwork and can't figure out why this one doesn't show edge library(visNetwork) nodes=data.frame(node=c('m1','m2','n1','n2')) a=data.frame(x=c('n1','n2'),y=c('m1','m2')) links=a%>% group_by(x,y)%>%tally() visNetwork(nodes, links) 回答1: From ?visNetwork : nodes: data.frame with nodes informations. Needed at least column "id". edges: data.frame with edges informations. Needed at least columns "from" and "to". So visNetwork( setNames(nodes, "id"), setNames(links, c("from", "to",

问题 How can I explicitly place nodes on a visNetwork graph? Or: How can I recreate that graphic in R using visNetwork or an alternative? Background: The ultimate goal is to represent Causal Loop Diagrams coming from Vensim files. Placing the nodes explicitly is just the first (crucial) step, because in Causal Loop Diagrams the visual mapping of nodes is part of the information (unlike in general graph theory). So if anybody has advice on the bigger picture aka. 'Bringing Causal Loop Diagram

问题 Is there a way to create groups of edges of a network? And can I select a group of edges that shows selected edges with nodes? Visualize with different colors and titles on an arrow is working manually. This works well with nodes like tutorial shows in the middle of that page: https://datastorm-open.github.io/visNetwork/options.html 来源： https://stackoverflow.com/questions/47204393/groups-of-edges-and-select-in-visnetwork-in-r

问题 The following code produces a nice network diagram: library(igraph);library(visNetwork);library(dplyr) set.seed(123) nnodes <- 10 nnedges <- 20 nodes <- data.frame(id = 1:nnodes) edges <- data.frame(from = sample(1:nnodes, nnedges, replace = T), to = sample(1:nnodes, nnedges, replace = T)) visNetwork(nodes, edges) %>% visIgraphLayout(layout = "layout_in_circle") %>% visNodes(shape="circle") %>% visOptions(highlightNearest = list(enabled = T, hover = T), nodesIdSelection = T) My question is:

问题 the below snapshot visual is created using the "visNetwork" package. My requirement here is that I have to hard code the edges and also after using visHierarchicalLayout(), I am not able to see them in order, Please help me with a dynamic approach such that no matter how many numbers, I get consecutive numbers in order without hard code. Thanks and please help. library(visNetwork) nodes <- data.frame(id = 1:7, label = 1:7) edges <- data.frame(from = c(1,2,3,4,5,6), to = c(2,3,4,5,6,7))

问题 If you run the R script below, the dataset "patients" is an eventlog of patients visiting a clinic and getting treatment. The trace explorer gets created as in the snapshot below with the tooltip displayed. Now in the "#Script for Frequency Percentage", you get the frequency percentage for each trace in the column "af_percent". My requirement is that, I just want to replace the "label = value" in the ggplot command below with corresponding frequency percentage of each trace. Please help.
