ng_2d()所属R语言包：RnavGraph
Visualization instruction for 2d scatterplots on a tk2d display
对于2D的散点图上一个tk2d的显示可视化指令
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Visualization instruction for a navGraph session that link the nodes of a navigation graph to 2d scatterplots and the edges to a 3d rigid rotation or a 4d transition.
链接导航图以二维散点图和一个三维的刚性旋转或4d过渡的边缘节点的navGraph届的可视化指令。
The scatterplots will be displayed on a tk2d display, provided by the RnavGraph package. tk2d allows the user to display dots, glyphs, text and images at given x-y positions. Further interactivity such as selection, zooming, brushing, changing colors and changing sizes are provided by the tk2d display. tk2d displays can also link data between different navGraph sessions.
的散点图，将显示上tk2d显示，由RnavGraph的软件包提供。 tk2d允许用户显示点，字形，在给定的xy位置的文本和图像。如选择的进一步的交互性，缩放，刷涂，改变颜色和改变体积中所提供由tk2d显示。 tk2d显示器，也可以连接不同的navGraph会议之间的数据。
用法----------Usage----------
ng_2d(data, graph, images = NULL, glyphs = NULL)
参数----------Arguments----------
参数：data
NG_data object.
NG_data对象。
参数：graph
NG_graph object.
NG_graph对象。
参数：images
NG_image object. Order of the images must match the order of the data in the NG_data object.
NG_image对象。订单的图像必须匹配的顺序数据在NG_data对象。
参数：glyphs
Vector of character strings matching either the names or shortnames of the NG_data object.
向量的字符串匹配的names或shortnamesNG_data对象。
Details
详细信息----------Details----------
The text labels in the tk2d display are taken from the labels slot in the NG_data object.
从标签插槽在NG_data对象的采取在tk2d显示的文本标签。
It the group slot of the NG_data object contains only colors from the colors function, objects get colored accordingly. Otherwise the group data gets mapped to some color key.
这组插槽的NG_data对象只包含颜色从colors功能，对象得到相应的颜色。否则，该组数据被映射到一些颜色键。
值----------Value----------
NG_Viztk2d object that inherits from the NG_Visualization class.
NG_Viztk2d对象，继承从NG_Visualization类的。

## NG_data[＃NG_data]
ng.iris <- ng_data(name = "iris", data = iris[,1:4],
shortnames = c('s.L', 's.W', 'p.L', 'p.W'),
group = iris$Species,
labels = substr(iris$Species,1,2))
## NG_graph[＃NG_graph]
G <- completegraph(shortnames(ng.iris))
LG <- linegraph(G, sep = "++")
ng.lg <- ng_graph("3d transition", LG, "++", "fruchtermanReingold" )
## NG_image[＃NG_image]
