Analysis in R: Different Colors, Different Colors, Different Colors! The “randomcoloR” package

Color not only affects the quality of materials, but is also profound, expressing feelings such as liking, disliking, and melancholy. We would like to introduce a package that allows you to create such “colors” randomly.

The following is an introduction to the “scales” package used in the “Execute command”. This package is recommended for expressing colors.
