If lm = TRUE, linear regression fits are shown for both y by x and x by y.

What is pair plot?

Pair Plots are a really simple (one-line-of-code simple!) way to visualize relationships between each variable. It produces a matrix of relationships between each variable in your data for an instant examination of our data.
