How can I create plots in R using different libraries?

You can use libraries like ggplot2, plotly, and lattice for plotting in R. Which one are you interested in?

I want to use ggplot2. Can you show me a simple example?

Sure! Here's a basic example:

library(ggplot2)

data(mpg)

ggplot(mpg, aes(x=displ, y=hwy)) +
  geom_point() +
  labs(title='Engine Displacement vs Highway MPG')

This will create a scatter plot of engine displacement against highway miles per gallon.

What if I want to customize the plot's appearance?

You can customize it using themes and additional parameters. For example:

ggplot(mpg, aes(x=displ, y=hwy)) +
  geom_point(color='blue', size=3) +
  labs(title='Engine Displacement vs Highway MPG') +
  theme_minimal()

This changes the point color and size and applies a minimal theme.

Can I save the plot to a file?

Yes! You can use the ggsave() function. For example:

ggsave('my_plot.png')

This will save the last plot you created as a PNG file.
