描述----------Description----------
A graph class where node and edge information is represented as an adjacency matrix. The adjacency matrix is square and element adjMat[i, j] is one if there is an edge from node i to node j and zero otherwise.
一个图的邻接矩阵表示节点和边缘信息的类。邻接矩阵是方形和元素adjMat[i, j]是一个从节点i到节点j，否则为零，如果有一个边缘。
Details
详情----------Details----------
The non-zero matrix values can be used to initialize an edge attribute. If this is desired, use the values argument in the call to new and provide a list with a single named element. The name determines the attributes and the value provides the default value for that attribute.
非零矩阵的值可以用来初始化一个边缘属性。如果此需要，可以使用调用values在new参数，并提供一个单一命名的元素列表。名称确定的属性和价值提供该属性的默认值。
类的对象----------Objects from the Class----------
Objects can be created by calls of the form new("graphAM", adjMat, edgemode, values).
创建对象可以通过检测的形式new("graphAM", adjMat, edgemode, values)。
插槽----------Slots----------
adjMat: An adjacency "matrix" describing the graph structure. The colnames of the matrix will be used as
adjMat：的邻接"matrix"的图形结构描述。 colnames矩阵将被用来作为
edgeData: Storage for edge attributes.
edgeData：边缘属性的存储。
nodeData: Storage for node attributes.
nodeData：存储节点的属性。

coerce signature(from = "graphAM", to = "matrix"): In converting to a matrix, if an edge attribute named "weight" is defined, the non-zero elements of the matrix will contain the corresponding attribute value. For more flexible
强迫signature(from = "graphAM", to = "matrix")：在转换到matrix，如果一个边缘的属性名为"weight"的定义，矩阵的非零元素将包含相应的属性值。更灵活的
coerce signature(from = "matrix", to = "graphAM"): This coerce method exists for symmetry. In most cases, creating a new graphAM instance using new gives one more
要挟signature(from = "matrix", to = "graphAM")：此要挟方法存在的对称性。在大多数情况下，创建一个新的graphAM例如使用new给人一种
