That error means that more 'grid' viewports have been popped than 
pushed.  Do you have a simple code sample that (sometimes) produces the 
error for me to try myself ?

I tested out the function for him and occasionally I get the error below. It happens sporadically using the exact same input as when it works normally. I have also encountered random errors like this in packages such as monocle and clusterProfiler. Does anyone know what may be the cause of this sporadic error? The version of ggplot2 I am running is "ggplot2_2.2.1".
