What does it mean by using aes(x = y) in ggplot
You can following code on page Code for Workshop: Introduction to Machine Learning with R.
gather(bc_data, x, y, clump_thickness:mitosis) %>%
ggplot(aes(x = y, color = classes, fill = classes)) +
geom_density(alpha = 0.3) +
facet_wrap( ~ x, scales = "free", ncol = 3)
What confused me is aes(x = y). The x on the left side of = is the parameter name, but the y on the right side is the value passed down from gather() ? If so, what is the value of y in the original parameter in aes()?
What is the correct way of understanding it?
