How can I compare different plots using ggplot2?

You can compare different plots in ggplot2 by layering them or using facets. What specific comparison are you looking to make?

I want to compare the distribution of two different variables.

You can use geom_density() to overlay density plots for each variable or facet_wrap() to create separate plots for each variable.

Can you show me an example code for that?

Sure! Here's a simple example:

library(ggplot2)

# Sample data
data <- data.frame(
  variable1 = rnorm(100),
  variable2 = rnorm(100, mean = 1)
)

# Overlay density plots
ggplot(data) + 
  geom_density(aes(x = variable1, fill = 'Variable 1'), alpha = 0.5) + 
  geom_density(aes(x = variable2, fill = 'Variable 2'), alpha = 0.5)
