描述----------Description----------

Create a graph object of class graphNEL or graphAM. You might also use the graph creating facility provided by the graph package.
创建图形对象类别graphNEL或graphAM。您还可以使用的图表创建提供graph包。


用法----------Usage----------

参数----------Arguments----------

参数：nodeNames
Numeric or character string vector.  
数字或字符串向量。


参数：mat
Either an adjacency matrix or a from to matrix.  
无论是邻接矩阵或以矩阵。


参数：weights
Numeric weights for edges. Either in the same order as the from to matrix or as a square matrix, depending what one have chosen for the mat argument.  
数字边的权重。无论是在相同的顺序从矩阵或作为一个方阵，这取决于人们已选择mat参数。


参数：directed
Logical value for defining a directed or undirected graph.  
定义有向或无向图的逻辑值。


参数：isAdjacency
If argument mat is adjacency matrix.  
如果参数垫是邻接矩阵。


参数：...
Currently not needed.  
目前没有必要的。


值----------Value----------

graphNEL or grapAM object.

实例----------Examples----------


## Using from to matrices[＃使用矩阵]
from <- c("A","A","C","C")
to   <- c("B","C","B","D")
ftEmat <- cbind(from,to)

## note how the E node is added[＃注意添加的E节点]
G <- newgraph(nodeNames = LETTERS[1:5], mat = ftEmat)

## say you would like to add weights to the graph[＃说你想添加到图形中的权重]
weights <- c(2,1,3,4)
G <- newgraph(nodeNames = LETTERS[1:5], mat = ftEmat, weights = weights)

## newgraph with adjacency matrix[＃newgraph用邻接矩阵]
V <- c('s.L', 's.W', 'p.L', 'p.W')
adjM <- matrix(c(0,1,1,0,1,0,1,1,1,1,0,0,0,1,0,0), ncol = 4)
all(adjM == t(adjM)) ## is symmetric (undirected)[＃是对称的（无向）]
G <- newgraph(nodeNames = V, mat= adjM, isAdjacency=TRUE)

## if you use adjacency matrices, you can add a matrix with weights[＃如果你使用邻接矩阵，你可以添加一个权重矩阵]
adjM <-     matrix(c(0,0,1,0,1,0,1,1,0,0,0,0,0,1,0,0), ncol = 4)
weightsM <- matrix(c(0,0,5,0,2,0,1,3,0,0,0,0,0,7,0,0), ncol = 4)
G <- newgraph(nodeNames = V, mat= adjM, weights = weightsM, directed = TRUE, isAdjacency=TRUE)
edgeData(G, attr = "weight")
