no result from heat map WGCNA

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(...)

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.
