（R Igraph）使用affilliation从邻接矩阵创建子图((R Igraph) Using affilliation to create subgraph from adjacency matrix)

 我需要通过附属数据选择邻接矩阵创建子图。 如何匹配邻接和联盟矩阵？ 
 
 采用以下邻接矩阵： 
 
    A   B   C   D   E   F   G
A   0   1   0   1   0   1   0
B   1   0   1   1   0   1   0
C   0   1   0   0   0   0   0
D   1   1   0   0   1   1   0
E   0   0   0   1   0   1   0
F   1   1   0   1   1   0   1
G   0   0   0   0   0   1   0
 
 以及从属关系矩阵： 
 
    P   R   Q
A   1   1   0
B   1   0   1
C   1   1   0
D   0   1   0
E   1   0   1
F   0   0   1
G   1   1   0
 
 如何仅使用隶属矩阵中与P对应的节点从邻接矩阵创建子图？ 

I need to create a subgraph from an adjacency matrix selecting by affiliation data. How do I match an adjacency and an affiliation matrix?
 
Take the following adjacency matrix:
 
    A   B   C   D   E   F   G
A   0   1   0   1   0   1   0
B   1   0   1   1   0   1   0
C   0   1   0   0   0   0   0
D   1   1   0   0   1   1   0
E   0   0   0   1   0   1   0
F   1   1   0   1   1   0   1
G   0   0   0   0   0   1   0
 
And the following affiliation matrix:
 
    P   R   Q
A   1   1   0
B   1   0   1
C   1   1   0
D   0   1   0
E   1   0   1
F   0   0   1
G   1   1   0
 
How do I create a subgraph from the adjacency matrix only with the nodes corresponding to P in the affiliation matrix?
