single plotting structure, function or \emph{any \R object with a

\code{plot} method} can be provided.}

if \code{x} is an appropriate structure.}

\item{\dots}{graphical parameters can be given as arguments to

17 |
\itemize{
|
|
|
18 |
\item \code{"p"} for \bold{p}oints,
|
|
|

\item \code{"l"} for \bold{l}ines,

|
|
20 |
\item \code{"b"} for \bold{b}oth,
|
|
|
21 |
\item \code{"c"} for the lines part alone of \code{"b"},
|
|
|
22 |
\item \code{"o"} for both \dQuote{\bold{o}verplotted},
|
|
|
23 |
\item \code{"h"} for \dQuote{\bold{h}istogram} like (or
|
|
|
24 |
\dQuote{high-density}) vertical lines,
|
|
|
25 |
\item \code{"s"} for stair \bold{s}teps,

|

26 |
\item \code{"S"} for other \bold{s}teps, see \emph{Details} below,

27 |
\item \code{"n"} for no plotting.

All other \code{type}s give a warning or an error; using, e.g.,

\code{type = "punkte"} being equivalent to \code{type = "p"} for S

For simple scatter plots, \code{\link{plot.default}} will be used.
|
|
|
45 |
However, there are \code{plot} methods for many \R objects,
|
|
|
46 |
including \code{\link{function}}s, \code{\link{data.frame}}s,
|
| 27447 |
ripley |
47 |
\code{\link[stats]{density}} objects, etc. Use \code{methods(plot)} and
|
| 27442 |
ripley |
48 |
the documentation for these.

The two step types differ in their x-y preference: Going from
|
|
|
51 |
\eqn{(x1,y1)} to \eqn{(x2,y2)} with \eqn{x1 < x2}, \code{type = "s"}
|
|
|
52 |
moves first horizontal, then vertical, whereas \code{type = "S"} moves
|
|
|
53 |
the other way around.
