labs

Modify axis, legend, and plot labels and then convert them with ggplotly

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p <-  p + labs(colour = "Cylinders")

plotly::ggplotly(p)

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p <-  p + labs(x = "New x label")

plotly::ggplotly(p)

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p <-  p + labs(title = "New plot title")

plotly::ggplotly(p)

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p <-  p + labs(title = "New plot title", subtitle = "A subtitle")

plotly::ggplotly(p)

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p <-  p + labs(caption = "(based on data from ...)")

plotly::ggplotly(p)

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p <-  p + labs(title = "title", tag = "A")
