Using pairs.panel() to look at (visualize) correlations between variables
Within the R ecosystem, there are different packages offering ways to represent correlations between variables in a dataset.
In a way, the powerful
plot() function, as seen in the previous recipe, can also be useful for correlation spotting, particularly when plotting all variables against one another (refer to the previous recipe for more details).
Nevertheless, among different alternatives, the one I think may give you a quicker and deeper understanding of the relationship between your data is the
