描述----------Description----------
Scanotstics assigns each possible scatterplot combination a weight for the attribute "Outlying", "Skewed", "Clumpy", "Sparse", "Striated", "Convex", "Skinny", "Stringy", "Monotonic".
Scanotstics分配给每一个可能的的散点图组合的权重属性“离岛”，“歪斜”，“块状”，“疏”，“条纹”，“凸”，“瘦”，“粘性” ，“单调”。
With scagNav one can start a navGraph session that constructs a navigation graph that shows certain properties most.
随着scagNav可以开始navGraph会话，构建了一个导航图，显示了一定的性能最。
See the vignette for more examples.

用法----------Usage----------
scagNav(data,
scags = c("Clumpy", "NotClumpy", "Monotonic", "NotMonotonic",
"Convex", "NotConvex", "Stringy", "NotStringy",
"Skinny", "NotSkinny", "Outlying","NotOutlying",
"Sparse", "NotSparse", "Striated", "NotStriated",
"Skewed", "NotSkewed"),
topFrac = 0.2, combineFn = NULL,
settings = NULL, glyphs = NULL,
images = NULL, sep = ":",
layout = "circle")
参数----------Arguments----------
参数：data
a single- or a list of objects generated by the ng_graph function. I.e. objects from the NG_data class.
一个单一的或listng_graph函数所产生的对象。即对象从NG_data类。
参数：scags
Single element or a subset of (with possible a "Not" preceding): <br> "Outlying", "Skewed", "Clumpy", "Sparse", "Striated",<br> "Convex", "Skinny", "Stringy", "Monotonic"
单元素的一个子集（可能是“不”前）：<BR>“离岛”，“歪斜”，“块状”，“疏”，“条纹”，参考“凸“，”瘦“，”粘性“，”单调“
参数：topFrac
Keep the nodes with the topFrac fraction of the scagnostic weights.
保留节点的topFrac部分的scagnostic权重。
参数：combineFn
Must be a function that takes in a vector of length scags and returns a single value. This return value comprises the new weights of the nodes get selected from.
必须是一个函数，需要在的向量长度scags，返回单个值。这个返回值，包括新的权重都被选择的节点。
参数：settings
a list of pailists. See the navGraph documentation.
列表pailists。请参阅navGraph文件。
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。
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：sep
Node names represent a set of variables whose name are separated by the character string sep (containing no spaces).
节点的名字所代表的一组变量名之间的字符串sep（不含空格）。
参数：layout
One of the following strings: "circle", "kamadaKawaiSpring", "fruchtermanReingold" or "random".
以下字符串之一：“圆”，“kamadaKawaiSpring”，“fruchtermanReingold”或“随机”。
值----------Value----------
navGraph handler.
navGraph处理程序。
