In each anatomic region, I would like to calculate the correlation between
Enzyme activity and each of the concentrations of Cu, Zn, Fe, and Ca, and
do a scatter plot with a tendency line, organizing those plots into a grid.
See the image below for the desired effect:

How can I achieve this?
Thank you in advance.
