text: user8784: I have created a heat map using WGCNA using R. But the heat map command is not showing the plot and there is no error. I have a large number of modules and traits. I am not sure if that is the reason. But I tried making it in HPC R and it still is not showing any result plot. Thank you!
  
  user650: The plot is probably being drawn to a device that you cannot view on a cluster. If you're using the plotNetworkHeatmap function, say, try something like this:
  png("plot.png", ...) #specify height, width, etc
  plotNetworkHeatmap(....) #call your function
  dev.off()
  
  Now, scp the plot.png file over to your local machine to view the plot.
  
  user9282: If you've copied over from some of the WGNCA tutorials you might have additionally copied the sizeGrWindow command - it's caused some of my plots to disappear.
  ie:
  sizeGrWindow(9,6)  # delete this line
  plot(...)
