Changing color of fontAwesome icons with visNetwork-CodePudding

I tried the example proposed in the

It seems that the alternative is to use the grouping option described in the documentation. However, I would want to have the data.frame option working as well and I can't figure out at the moment what I do wrong above.

nodes <- data.frame(id = 1:3, 
                    shape = "icon", 
                    group = c("A", "B", "C"))
edges <- data.frame(from = c(1,2), to = c(2,3))

visNetwork(nodes, edges) %>%
  visGroups(groupname = "A", shape = "icon", 
            icon = list(code = "f1ad", color = "#800000")) %>%
  visGroups(groupname = "B", shape = "icon", 
            icon = list(code = "f015", color = "#0000ff")) %>%
  visGroups(groupname = "C", shape = "icon", 
            icon = list(code = "f007", color = "#ffa500")) %>%
  addFontAwesome()

CodePudding user response：

Change color to icon.color and everything works:

library(visNetwork)

nodes <- data.frame(id = 1:3, 
                    shape = "icon", 
                    icon.face = "FontAwesome",
                    icon.color = c("#800000", "#0000ff", "#ffa500"), # doesn't have any effect on icon color
                    icon.code = c("f1ad", "f015", "f007"))
edges <- data.frame(from = c(1,2), to = c(2,3))

visNetwork(nodes, edges) %>%
  addFontAwesome()
