使用visNetwork动态更新R中的节点 [英] Using visNetwork to dynamically update nodes in R

问题描述

以下快照视觉是使用"visNetwork"包创建的.我在这里的要求是，我必须对边缘进行硬编码，并且在使用visHierarchicalLayout()之后，我无法按顺序看到它们，请以动态方式帮助我，无论有多少个数字，我都会得到连续的数字没有硬代码的订单.谢谢，请帮忙.

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))
visNetwork(nodes, edges, width = "100%") %>% 
visEdges(arrows = "to") %>% 
visHierarchicalLayout()

推荐答案

使用级别属性可以完成此任务，它会根据给定的顺序对齐网络.

Using level attribute does the job, it aligns the network based on the order given.

library(visNetwork)
nodes <- data.frame(id = 1:7, label = 1:7, level = 1:7)
# Extract the id
num <- nodes$id
# Repeat the numbers
num2 <- rep(num, each = 2)
# Remove the first and last numbers
num3 <- num2[c(-1, -length(num2))]
#Create a data frame
edges <- as.data.frame(matrix(num3, ncol = 2, byrow = TRUE))
names(edges) <- c("from", "to")
visNetwork(nodes, edges, width = "100%") %>% 
visEdges(arrows = "to") %>% 
visHierarchicalLayout()
