Colour by and size by different matrices

[lucygarner]

Hi,

Thank you for generating this great function. I would like to be able to generate a correlation plot that is coloured by the correlation values, but the squares (or preferably circles) are sized by a different matrix. Is this possible using ggcorrplot or if not, does anyone have any suggestions as to how I can do this in ggplot2? I have tried a few different ways, but haven't managed to achieve what I am looking for?

Best, Lucy
