scale_shape_identity(..., guide = "none")
scale_linetype_identity(..., guide = "none")

\item{...}{Other arguments passed on to \code{\link{discrete_scale}} or
\code{\link{continuous_scale}}}

\description{
Use values without scaling.

\examples{
colour <- c("red", "green", "blue", "yellow")
qplot(1:4, 1:4, fill = colour, geom = "tile")
qplot(1:4, 1:4, fill = colour, geom = "tile") + scale_fill_identity()
# To get a legend guide, specify guide = "legend"
qplot(1:4, 1:4, fill = colour, geom = "tile") +
scale_fill_identity(guide = "legend")
# But you'll typically also need to supply breaks and labels:
qplot(1:4, 1:4, fill = colour, geom = "tile") +
scale_fill_identity("trt", labels = letters[1:4], breaks = colour,
guide = "legend")
# cyl scaled to appropriate size
qplot(mpg, wt, data = mtcars, size = cyl)
# cyl used as point size
qplot(mpg, wt, data = mtcars, size = cyl) + scale_size_identity()
