Calculate the minimum, maximum, medium, standard deviation of ALL the correlations, except those correlations which are equal to $1$ in the diagonal cells in the heatmap. $($Hints: use functions in R instead of finding them in the heatmap visually. Use the summary$($cor$.$mat$)$ will get the min, max and medium

This question is being asked of this dataset, but I am not sure I really understnand what is meant by it$.$ We are suppose to use R programming.

I also have a heatmap, but not sure what do with it$.$
