folks! I want to insert pictures instead of nodes on the graph. I used the visNetwork library on the vis.js engine. While searching the answer I found the article https://datastorm-open.github.io/visNetwork/image_icon.html, but I've tried to repeat written code myself, unfortunately it didn't draw nodes as images in Rstudio.
setwd("/home/user/")
path_to_images<-"Images/"
nodes <- data.frame(id = 1:4,
shape = c("image", "circularImage"),
image = paste0(path_to_images, 1:4, ".png"),
label = "I'm an image")
edges <- data.frame(from = c(2,4,3,3), to = c(1,2,4,2))
visNetwork(nodes, edges, width = "100%") %>%
visNodes(shapeProperties = list(useBorderWithImage = TRUE)) %>%
visLayout(randomSeed = 2)
Maybe the problem is in local path to images? I'll wait for answer, thanks!)
I've found the answer on my question. On my view the problem was in path to the images. I installed apache2 server on my ubuntu 18.04 and created a directory with photos,and then I've just changed the path_to_images variable on "http:127.0.0.1/Images/" and added an brokenImage option in visNodes:
visNetwork(nodes, edges, width = "100%") %>%
visNodes(shapeProperties = list(useBorderWithImage = TRUE),
brokenImage="http://localhost/Images/erroe.png") %>%
visLayout(randomSeed = 2)
And it finally started to work!)
