详细信息----------Details----------
This is the plot method for the class owin. The action is to plot the boundary of the window on the current plot device, using equal scales on the x and y axes.
这是plot方法的类owin。该行动是对当前的打印设备，使用x和y轴平等的尺度上绘制窗口边界。
If the window x is of type "rectangle" or "polygonal", the boundary of the window is plotted as a polygon or series of polygons. If x is of type "mask" the discrete raster approximation of the window is displayed as a binary image (white inside the window, black outside).
如果该窗口x的类型是"rectangle"或"polygonal"，在窗口的边界被绘制为一个多边形或一系列的多边形。如果x是类型"mask"的离散栅格近似的窗口显示为一个二进制图像（白色的窗口内，外黑）。
Graphical parameters controlling the display (e.g. setting the colours) may be passed directly via the ... arguments, or indirectly reset using spatstat.options.
通过...参数，控制显示（例如，设置颜色）的图形参数直接传递或间接复位spatstat.options。
When x is of type "rectangle" or "polygonal", it is plotted by the R function polygon. To control the appearance (colour, fill density, line density etc) of the polygon plot, determine the required argument of polygon and pass it through ... For example, to paint the interior of the polygon in red, use the argument col="red". To draw the polygon edges in green, use border="green". To suppress the drawing of polygon edges, use border=NA.
当x是类型"rectangle"或"polygonal"，它绘制的R功能polygon。要控制的多边形图的外观（颜色，填充密度，线密度等），确定所需的参数polygon并把它传递通过...例如，画多边形内部的红色，使用参数col="red"。要绘制的多边形边的绿色，使用border="green"。为了抑制绘制多边形的边，使用border=NA。
When x is of type "mask", it is plotted by image.default. The appearance of the image plot can be controlled by passing arguments to image.default through .... The default appearance can also be changed by setting the parameter par.binary of spatstat.options.
当x是的类型"mask"，，绘制image.default。图像绘图的外观可以通过传递参数给image.default通过...。默认的外观也可以改变设置的参数par.binaryspatstat.options。
To zoom in (to view only a subset of the window at higher magnification), use the graphical arguments xlim and ylim to specify the desired rectangular field of view. (The actual field of view may be larger, depending on the graphics device).
放大（只查看窗口的一个子集，在更高的放大倍率），使用图形化的参数xlim和ylim到指定所需的矩形视野。 （实际视场的可能较大，取决于在图形设备上）。

none.
没有。
与孔填充多边形的注意事项----------Notes on Filled Polygons with Holes----------
The function polygon can only handle polygons without holes. To plot polygons with holes in a solid colour, we have implemented two workarounds.
函数polygon只能处理无孔的多边形。要绘制的多边形孔在一个坚实的颜色，我们已经实现了两个解决方法。
The first workaround uses the relatively new function polypath which does have the capability to handle polygons with holes. However, not all graphics devices support polypath. The older devices xfig and pictex do not support polypath. On a Windows system, the default graphics device windows supports polypath. On a Linux system, the default graphics device X11(type="Xlib") does not support polypath but X11(type="cairo") does support it. See X11 and the section on Cairo below.
第一个解决方法使用相对较新的功能polypath有能力处理的多边形孔。然而，并非所有的图形设备的支持polypath。的旧设备xfig和pictex不支持polypath。在Windows系统上，显卡的默认设备windows支持polypath。在Linux系统中，显卡的默认设备X11(type="Xlib")不支持polypath但X11(type="cairo")不支持它。见X11和开罗以下的部分。
The other workaround requires use of the gpclib package which effects a triangulation of the polygonal window in question which in turn permits the plotting of the window, filled with a solid colour, without filling the holes. Type licence.polygons() for information about the licence under which gpclib operates. To make use of this workaround you need to have the packagegpclib installed and to set spatstat.options(gpclib=TRUE) (and to be working under circumstances permitted by the gpclib licence).
其他的解决方法需要使用的gpclib包，一个三角的多边形窗口的问题，又允许的绘图窗口，用纯色填充，而填充孔的影响。输入licence.polygons()下，gpclib经营许可证的信息。要使用此变通办法，你需要安装packagegpclib的设置spatstat.options(gpclib=TRUE)（和gpclib许可证允许的情况下）。
在Linux系统上的Cairo图形----------Cairo graphics on a Linux system----------
Linux systems support the graphics device X11(type="cairo") (see X11) provided the external library cairo is installed on the computer. See http://www.cairographics.org/download for instructions on obtaining and installing cairo. After having installed cairo one needs to re-install R from source so that it has cairo capabilites. To check whether your current installation of R has cairo capabilities, type (in R) capabilities()["cairo"]. The default type for X11 is controlled by X11.options. You may find it convenient to make cairo the default, e.g. via your .Rprofile. The magic incantation to put into .Rprofile is
Linux系统支持的图形设备X11(type="cairo")（见X11）提供了外部库cairo已安装在电脑上。请参阅http://www.cairographics.org/download获取和安装cairo的说明。安装后cairo需要重新安装R源，因此，它有cairo满足您。要检查是否您的当前安装的Rcairo功能，类型（R）capabilities()["cairo"]。的默认类型X11控制X11.options。您可能会发现它方便cairo默认情况下，例如：通过您的.Rprofile。神奇的咒语投入.Rprofile
