\title{Convenience functions to set the limits of the x and y axis.}
\usage{
xlim(...)

ylim(...)
}
\arguments{
\item{...}{if numeric, will create a continuous scale, if factor or
character, will create a discrete scale.}
}
\description{
Observations not in this range will be dropped completely and
not passed to any other layers.  If a NA value is substituted for one of the
limits that limit is automatically calculated.
}
\examples{
# xlim
xlim(15, 20)
xlim(20, 15)
xlim(c(10, 20))
xlim("a", "b", "c")
qplot(mpg, wt, data=mtcars) + xlim(15, 20)
# with automatic lower limit
qplot(mpg, wt, data=mtcars) + xlim(NA, 20)

# ylim
ylim(15, 20)
ylim(c(10, 20))
ylim("a", "b", "c")
qplot(mpg, wt, data=mtcars) + ylim(0, 4)
# with automatic upper limit
qplot(mpg, wt, data=mtcars) + ylim(0, NA)
}

  observations, see \code{\link{coord_cartesian}}.
