I have a gene-gene correlation matrix of about 20,000 genes by 20,000 genes. I am trying to generate a heatmap similar to how JMP can create plots like this:

I want to see how the resulting data will look. Unfortunately, as I was typing this R Studio Aborted the session as it was trying to generate the heatmap. Too much to handle?
Alternatively, I was advised to plot genes by principle components. I may be leaning towards this approach now... unless someone knows a solution to this. I do have a decent amount of cores (16) and and decent amount of RAM 128GB.
Any help would be appreciated.
