In R, How can I compare two continuous variables and indicating two categorical variables in a chart

Question

For example, lets say I want a plot that compares cost and score of two age groups, and the plot should also indicate their gender.

What plot can I use and how can each attribute be distinguished?

Answer 1

You could use ggplot2 .

Eg using the mtcars data:

ggplot(mtcars, aes(x = hp, y = mpg, shape = factor(vs), size = cyl)) + geom_point()
