Description

Change axis labels, legend titles, plot title/subtitle and below-plot caption.

Usage

labs(...)

xlab(label)

ylab(label)

ggtitle(label, subtitle = NULL)

Arguments

...

a list of new names in the form aesthetic = "new name"

label

The text for the axis, plot title or caption below the plot.

subtitle

the text for the subtitle for the plot which will be displayed below the title. Leave NULL for no subtitle.

Examples

p <- ggplot(mtcars, aes(mpg, wt)) + geom_point()
p + labs(title = "New plot title")
p + labs(x = "New x label")
p + xlab("New x label")
p + ylab("New y label")
p + ggtitle("New plot title")

# Can add a subtitle to plots with either of the following
p + ggtitle("New plot title", subtitle = "A subtitle")
p + labs(title = "New plot title", subtitle = "A subtitle")

# Can add a plot caption underneath the whole plot (for sources, notes or
# copyright), similar to the \code{sub} parameter in base R, with the
# following
p + labs(caption = "(based on data from ...)")

# This should work independently of other functions that modify the
# the scale names
p + ylab("New y label") + ylim(2, 4)
p + ylim(2, 4) + ylab("New y label")

# The labs function also modifies legend labels
p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p + labs(colour = "Cylinders")

# Can also pass in a list, if that is more convenient
p + labs(list(title = "Title", subtitle = "Subtitle", x = "X", y = "Y"))
