There are already many questions about this on this site, e.g. this one: plot from sankeyNetwork in networkD3 does not show output neither generates any warning/error in R but my issues seems to be something else than what is written in the accepted answer.

The curious thing is that this problem (no plot, but no error message either) already appears in below example that is copied literally from the internet:

nodes = data.frame("name" = 
                     c("Node A", # Node 0
                       "Node B", # Node 1
                       "Node C", # Node 2
                       "Node D"))# Node 3
links = as.data.frame(matrix(c(
  0, 1, 10, # Each row represents a link. The first number
  0, 2, 20, # represents the node being conntected from. 
  1, 3, 30, # the second number represents the node connected to.
  2, 3, 40),# The third number is the value of the node
  byrow = TRUE, ncol = 3))
names(links) = c("source", "target", "value")
sankeyNetwork(Links = links, Nodes = nodes,
              Source = "source", Target = "target",
              Value = "value", NodeID = "name",
              fontSize= 12, nodeWidth = 30)

I assume that the person who wrote that website did get their plot, but on my computer it is not working. I hope there is a simple explanation.

• 3 This code runs perfectly fine on my end. You can check your package version packageVersion("networkD3"), it should be ‘0.4’. Can you give us a quick sessionInfo()? – Tim G Commented Mar 7 at 12:11
• 2 This may also be due to a known issue with R 4.4.0. You can either download the patched version or upgrade your R version outright and it should work. – cristian-vargas Commented Mar 7 at 15:27

As predicted by  cristian-vargas in the comments, upgrading to R version 4.4.3 fixed the issue!
