How can I add annotations to my ggplot2 graphs?

You can use the annotate() function in ggplot2 to add text, shapes, or images to your plots. What type of annotation are you looking to add?

I want to add a text label to a specific point on my scatter plot.

You can specify the x and y coordinates of the point and use annotate('text', x, y, label='Your Label'). Do you have the coordinates in mind?

Yes, I want to label the point at (3, 5). How would that look in code?

It would look like this: annotate('text', x=3, y=5, label='Your Label'). You can also adjust the size and color of the text if needed.

Thanks! Can I also add arrows pointing to the annotation?

Absolutely! You can use geom_segment() to draw arrows. Combine it with annotate() for a complete effect.
