Scaling for heatmaps

[ikremsky]

Hi. Could you lease explain how scaling is done for heatmaps. I do not see any explanation anywhere in the documentation. If it uses the scale() function from R, I am still unsure how scaling is done. For example, when "global" is selected, does that mean that each region is shifted based on the global mean and scaled based on the global sd, or is it simple that each heatmap is still scaled independently and simply presented in the same range of values?

Also, when selecting a custom range of scaling values, does it do the scaling independently for each heatmap before plotting on the custom range? If so, is there any way to do a global scaling and plot on a custom range of values?

Thanks!
