Visualize does not complete

[gluc]

Hmm, that's a tough one. My guess would be that it's a problem in DiagrammeR. I had previously experienced problems with special characters in node names, for instance. If you prepare a reproducible example, I might be able to help, no promises though :-(

The first time I ran this "reproducible" example, the visualization succeeded. Subsequent runs, however, failed. Stopping and restarting R and RStudio did not repair the state. So I post here a small example and model file to learn if others experience the same sort of non-determinism.

library(ahp)
ahpName <- "model.txt" # text suffix for issue posting
if (! file.exists(ahpName)) {
  stop(paste("Cannot find AHP file",ahpName))
}

myAhp <- Load(ahpName)

# calculate
Calculate(myAhp)

# visualize -- fails
Visualize(myAhp)

# analyze -- succeeds


Analyze(myAhp)
AnalyzeTable(myAhp)
