(optional) numeric vector of values of the graphical parameter lty controlling the line style of each plot.

参数：...
Extra arguments passed to plot.default.

参数：ylim.covers
Optional vector of y values that must be included in the y axis. For example ylim.covers=0 will ensure that the y axis includes the origin.
可选矢量y值必须包含在y轴。例如ylim.covers=0将确保y轴的起源。
参数：legend
Logical flag or NULL. If legend=TRUE, the algorithm plots a legend in the top left corner of the plot, explaining the meaning of the different line types and colours.
逻辑标志或NULL。如果legend=TRUE，该算法绘制传说中左上角的图，解释不同的线路类型和颜色的含义。
参数：legendpos
The position of the legend. Either a character string keyword (see legend for keyword options) or a pair of coordinates in the format list(x,y). Alternatively if legendpos="float", a location will be selected inside the plot region, avoiding the graphics.
位置的传说。无论是字符串关键字（见legend关键字选项）或一对坐标的格式list(x,y)。另外，如果legendpos="float"，位置将被选中里面的图区域，避免了图形。
参数：legendavoid
Whether to avoid collisions between the legend and the graphics. Logical value. If TRUE, the code will check for collisions between the legend box and the graphics, and will override legendpos if a collision occurs. If FALSE, the value of legendpos is always respected.
无论以避免冲突的传说和图形之间。逻辑值。如果TRUE，代码将检查的传说框和图形之间的碰撞，将覆盖legendpos如果发生冲突。如果FALSE，legendpos始终尊重。
参数：legendmath
Logical. If TRUE, the legend will display the mathematical notation for each curve. If FALSE, the legend text is the identifier (column name) for each curve.
逻辑。如果TRUE，传说中会显示为每条曲线的数学符号。如果FALSE，图例文本是为每条曲线的标识符（列名）。
参数：legendargs
Named list containing additional arguments to be passed to legend controlling the appearance of the legend.
命名列表，其中包含额外的参数传递给legend控制外观的传说，。
参数：shade
An index that identifies two columns of x. When the corresponding curves are plotted, the region between the curves will be shaded in light grey. Often used for displaying simulation envelopes, by setting shade=c("hi", "lo").
一个索引，可识别两列x。当对应的曲线绘制的曲线之间的区域将被以浅灰色阴影。通常用于显示模拟的信封，，通过设置shade=c("hi", "lo")。
参数：shadecol
The colour to be used in the shade plot. A character string or an integer specifying a colour.
要使用的颜色在shade图。一个字符串或一个整数，指定一种颜色。
参数：add
Logical. Whether the plot should be added to an existing plot
逻辑。图是否应该被添加到现有的图
参数：limitsonly
Logical. If FALSE, plotting is performed normally. If TRUE, no plotting is performed at all; just the x and y limits of the plot are computed and returned.
逻辑。如果FALSE，绘制正常进行。如果TRUE，没有策划执行;只是x和y限制的图，计算并返回。

详细信息----------Details----------
This is the plot method for the class "fv".
这是plot方法的类"fv"。
The use of the argument fmla is like plot.formula, but offers some extra functionality.
该使用的参数fmla的像plot.formula，但提供了一些额外的功能。
The left and right hand sides of fmla are evaluated, and the results are plotted against each other (the left side on the y axis against the right side on the x axis).
的左和右手侧的fmla进行评估，其结果绘制互相反对（y轴对右侧x轴左侧）。
The left and right hand sides of fmla may be the names of columns of the data frame x, or expressions involving these names. If a variable in fmla is not the name of a column of x, the algorithm will search for an object of this name in the environment where plot.fv was called, and then in the enclosing environment, and so on.
的左和右手侧的fmla可能是数据框x，或涉及这些名称的表达式的列的名称。如果一个变量在fmla是不是一列x的名称，该算法将搜索这个名字对象的环境下，plot.fv被称为，然后在封闭的环境，等等。
Multiple curves may be specified by a single formula of the form cbind(y1,y2,...,yn) ~ x, where x,y1,y2,...,yn are expressions involving the variables in the data frame. Each of the variables y1,y2,...,yn in turn will be plotted against x. See the examples.
多条曲线，可以指定一个公式的形式cbind(y1,y2,...,yn) ~ x，其中x,y1,y2,...,yn是涉及到的数据框中的变量的表达式。的每一个变量y1,y2,...,yn反过来将被绘制对x。见的例子。
Convenient abbreviations which can be used in the formula are
方便可以在公式中使用的缩写是
the symbol . which represents all the variables in the data frame (other than the function argument itself);
符号.代表所有的数据框中的变量（函数的参数本身以外）;
the symbol .x which represents the function argument;
符号.x它代表了函数的参数;
the symbol .y which represents the recommended value of the function.
符号.y代表建议值的功能。
The value returned by this plot function indicates the meaning of the line types and colours in the plot. It can be used to make a suitable legend for the plot if you want to do this by hand. See the examples.
该图函数的返回值线类型和颜色在图中表示的含义。它可以用来做一个合适的传说的图，如果你想做到这一点的手。见的例子。
The argument shade can be used to display critical bands or confidence intervals. If it is not NULL, then it should be a subset index for the columns of x, that identifies exactly 2 columns. When the corresponding curves are plotted, the region between the curves will be shaded in light grey. See the Examples.
参数shade可用于显示重要的乐队或置信区间。如果它不是NULL，那么它应该是指数为列x，标识完全相同2列的一个子集。当对应的曲线绘制的曲线之间的区域将被以浅灰色阴影。请参阅范例。
The default values of lty, col and lwd can be changed using spatstat.options("plot.fv").
默认值lty，col和lwd，可以改变spatstat.options("plot.fv")。
Use type = "n" to create the plot region and draw the axes without plotting any data.
使用type = "n"创建的图区域，并绘制轴的不绘制任何数据的情况下。
Use limitsonly=TRUE to suppress all plotting and just compute the x and y limits. This can be used to calculate common x and y scales for several plots.
使用limitsonly=TRUE抑制所有策划和计算x和y限制。这可以用来计算几个图的共同x和y尺度。
值----------Value----------
Either NULL, or a data frame giving the meaning of the different line types and colours.
无论哪种NULL，或一个数据框给出的不同的线路的类型和颜色的含义。
