How can I compare different visualizations in ggplot2?

You can compare visualizations in ggplot2 by creating multiple plots and arranging them using functions like gridExtra::grid.arrange() or patchwork. Would you like an example?

Yes, please provide an example of comparing a scatter plot and a bar plot.

Sure! Here's a simple example:

library(ggplot2)
library(gridExtra)

# Scatter plot
scatter_plot <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() + ggtitle('Scatter Plot')

# Bar plot
bar_plot <- ggplot(mtcars, aes(x=factor(cyl))) + geom_bar() + ggtitle('Bar Plot')

# Arrange plots
grid.arrange(scatter_plot, bar_plot, ncol=2)

This will display both plots side by side.

What if I want to add titles and labels to each plot?

You can customize titles and labels within each ggplot call. For example:

scatter_plot <- ggplot(mtcars, aes(x=wt, y=mpg)) + 
  geom_point() + 
  ggtitle('Weight vs MPG') + 
  xlab('Weight (1000 lbs)') + 
  ylab('Miles per Gallon')

bar_plot <- ggplot(mtcars, aes(x=factor(cyl))) + 
  geom_bar() + 
  ggtitle('Count of Cars by Cylinder') + 
  xlab('Number of Cylinders') + 
  ylab('Count')

This will enhance the clarity of your visualizations.
