How can I change the title of a ggplot2 legend?

Question

I was looking here but I can\'t figure it out.

How can I change the word \"type\" to something else?

Answer 1

Add either:

+ scale_fill_discrete(name="Title", labels=c("1","2","3"))

or

+ scale_colour_discrete(name="Title", labels=c("1","2","3"))

depending on the geom.

I recommend you look into the ggplot2 cheatsheet. https://www.rstudio.com/wp-content/uploads/2015/03/ggplot2-cheatsheet.pdf
