How can I create advanced visualizations using ggplot2?

You can create advanced visualizations in ggplot2 by using layers, themes, and custom scales. What specific visualization are you interested in?

I want to create a scatter plot with a regression line.

You can use the geom_point() function for the scatter plot and geom_smooth(method='lm') for the regression line. Would you like an example code?

Yes, please provide the example code.

Here's a simple example:

library(ggplot2)

data(mtcars)

ggplot(mtcars, aes(x=wt, y=mpg)) + 
  geom_point() + 
  geom_smooth(method='lm')

This will create a scatter plot of weight vs. miles per gallon with a regression line.

How can I customize the colors and themes of the plot?

You can customize colors using the scale_color_manual() function and themes with theme_minimal(), for example. Would you like to see a specific customization?
