\arguments{
\item{...}{A list of new name-value pairs. The name should be an aesthetic.}

\item{title}{The text for the title.}

\item{subtitle}{The text for the subtitle for the plot which will be
displayed below the title.}

\item{caption}{The text for the caption which will be displayed in the
bottom-right of the plot by default.}

\item{tag}{The text for the tag label which will be displayed at the
top-left of the plot by default.}

\item{alt, alt_insight}{Text used for the generation of alt-text for the plot.
See \link{get_alt_text} for examples.}

\item{label}{The title of the respective axis (for \code{xlab()} or \code{ylab()}) or
of the plot (for \code{ggtitle()}).}

\description{
Good labels are critical for making your plots accessible to a wider
audience. Always ensure the axis and legend labels display the full
variable name. Use the plot \code{title} and \code{subtitle} to explain the
main findings. It's common to use the \code{caption} to provide information
about the data source. \code{tag} can be used for adding identification tags
to differentiate between multiple plots.
}
\details{
You can also set axis and legend labels in the individual scales (using
the first argument, the \code{name}). If you're changing other scale options, this
is recommended.

If a plot already has a title, subtitle, caption, etc., and you want to
remove it, you can do so by setting the respective argument to \code{NULL}. For
example, if plot \code{p} has a subtitle, then \code{p + labs(subtitle = NULL)} will
remove the subtitle from the plot.

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

# The plot title appears at the top-left, with the subtitle
# display in smaller text underneath it
p + labs(title = "New plot title")
p + labs(title = "New plot title", subtitle = "A subtitle")

# The caption appears in the bottom-right, and is often used for
# sources, notes or copyright
p + labs(caption = "(based on data from ...)")

# The plot tag appears at the top-left, and is typically used
# for labelling a subplot with a letter.
p + labs(title = "title", tag = "A")

# If you want to remove a label, set it to NULL.
p +
 labs(title = "title") +
 labs(title = NULL)
