ggplot2 - Adjust plot titles labels

Question

How to edit the label alignment and position of text in ggplots? What do hjust and vjust do?

Answer 1

Vjust and hjust attributes are used to set the position of text or labels wrt axis in ggplot.

See below for a better understanding.

> ggplot(mpg,aes(cyl))+geom_bar(stat = "count")+ggtitle("GGplot")

> ggplot(mpg,aes(cyl))+geom_bar(stat = "count")+ggtitle("GGplot")+theme(axis.title = element_text(hjust = 1))
