描述----------Description----------
Plot self-organising map, obtained from function wccsom. Several types of plots are supported.
图自组织映射，获得的功能wccsom。支持几种类型的图。
用法----------Usage----------
## S3 method for class 'wccsom'
plot(x, type = c("changes", "codes", "counts", "mapping",
"prediction", "property", "quality"),
classif = NULL, labels = NULL, pchs = NULL, main = NULL,
palette.name = heat.colors, ncolors, unit.colors,
unit.bgcol = NULL, zlim = NULL, property = NULL,
heatkey=TRUE, contin, ...)
参数----------Arguments----------
参数：x
SOM object.
SOM对象。
参数：type
Type of plot. (Wow!)
图类型。 （哇！）
参数：classif
classification object, as returned by wccassign. Only needed if type equals '"mapping"', '"quality"', and '"counts"'. Also a vector of class numbers may be given. If the network was trained with keep.data equal to TRUE, then the object already contains this information.
分类对象，返回的wccassign。仅在需要type等于“映射”，“质量”，和“计数”。也是一个向量类的数字。如果网络进行训练keep.data等于TRUE，则该对象已经包含了这个信息。
参数：labels
(optional) labels to plot when type equals '"mapping"'.
（可选）绘制时type等于“映射”的标签。
参数：pchs
(optional) plotting symbols to use when type equals '"mapping"'.
（可选）绘制的符号使用时type等于“映射”。
参数：main
title of the plot.
标题的图。
参数：palette.name
colors to use as unit background for '"codes"', '"counts"', '"prediction"', '"property"' and '"quality"' plotting types.
颜色使用单位背景的“代码”，“计数”，“预测”，“财产”和“质量”绘图类型。
参数：ncolors
number of colors to use in the palette.
在调色板中使用的颜色数。
参数：unit.colors
explicit definition of the colors for the units in the '"codes"', '"counts"', '"prediction"', '"property"' and '"quality"' plotting types.
明确定义为单位在“代码”，“计数”，“预测”，“财产”和“质量”绘图类型的颜色。
参数：unit.bgcol
background color for units if no other color information is to be plotted. For plotting type is '"codes"', the default is '"transparent"'; in other cases the default is '"gray"'.
背景颜色的单位，如果没有其他的颜色信息被绘制。绘图类型是“代码”，默认是“透明的”，在其他情况下，默认是“灰色”。
参数：zlim
Optional range for color coding of unit backgrounds.
单位背景颜色编码的可选范围。
参数：property
Values to use if the '"property"' plotting type. Can be used for colouring units in general.
使用的“”属性“”绘图类型的值。可用于着色单元一般。
参数：heatkey
Whether or not to generate a heatkey at the left side of the plot in the '"quality"', '"counts"', and '"property"' plotting types.
是否生成heatkey在“质量”的图的左侧，“计数”，和“”属性“，”绘图类型。
参数：contin
Whether the heatkey should show a range of values (TRUE) or a series of discrete values. The function tries to make a good guess; in case of strange-looking results it may pay to explicitly provide a value for this argument.
无论的heatkey应该显示的范围内的值（TRUE）或一系列离散值。函数试图做出很好的猜测，奇怪的前瞻性结果的情况下，它可能要明确规定此参数的值。
参数：...
Other graphical parameters, e.g. colours of labels in the '"mapping"' plotting type.
其他的图形化的参数，例如“映射”标签中的颜色“绘图类型。
Details
详细信息----------Details----------
Several different types of plots are supported:
支持几种不同类型的图：
'"changes"' Shows the mean change in similarity to the best matching codebook vector for each epoch. Since codebook vectors become more similar to the data that are mapped to them, the changes should always be positive. Upon convergence, the changes
“变化”显示相似的最佳匹配码本矢量的每个划时代的平均变化。由于码本向量变得更类似于被映射到它们的数据，变更应始终是正的。在收敛，
'"codes"' Shows the codebook vectors.
“代码”显示的码本向量。
'"counts"' Shows the number of objects mapped to the
“计数”映射到显示的对象的数量
'"mapping"' Show where a set of objects is mapped. It
“映射”显示一组对象的映射。它
'"prediction"' Shows predictions for units; if no '"property"' argument is given, the function will for supervised maps the predictions for every unit; for unsupervised maps, where this
“预测”显示为单位的预测，如果没有“财产”的说法是，该功能将受监督的图的预测，每单位的无监督的图，
'"property"' Plot a map with the units coloured according to a specific property. The standard application is to precompute the similarities of an object to all units in the map, and plot these with a colour key. Also other quantities may be
“”属性“”彩色根据特定的属性单位绘制的图。该标准的应用程序是预先计算的相似性对象的所有单位，并在图上绘制这些与一个彩色键。也可能是其他数量
'"quality"' Shows the units coloured according to the mean agreement (WCC) of mapped objects to the unit vector. A colour key is plotted on the left. The variation in the WCCs of the mapped objects is indicated by the blue line: if it is pointing downwards it
“质量”显示单元根据平均协议（WCC）的单位向量的映射对象着色。一种彩色键绘制在左边。 WCCS的映射对象的变化，蓝线表示：如果是朝下
值----------Value----------
If type equals '"property"', the wcc values for all units
如果type等于财产“，各单位的WCC值
