Find the Central Graph of a Labeled Graph Stack
中央图形的标记图堆栈
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Returns the central graph of a set of labeled graphs, i.e. that graph in which i->j iff i->j in >=50% of the graphs within the set. If normalize==TRUE, then the value of the i,jth edge is given as the proportion of graphs in which i->j.
返回中央标签图形的一组曲线,即该图中,其中i-> j的,当且仅当ı-> j在> = 50%内的设定的曲线图。如果normalize==TRUE,然后第i,j个边缘是作为图形的比例,其中i-> j的。
用法----------Usage----------
centralgraph(dat, normalize=FALSE)
参数----------Arguments----------
参数:dat
one or more input graphs.
一个或多个输入图表。
参数:normalize
boolean indicating whether the results should be normalized. The result of this is the "mean matrix". By default, normalize==FALSE.
布尔值,指示是否应该归的结果。这样做的结果是“均值矩阵”。默认情况下,normalize==FALSE。
Details
详细信息----------Details----------
The central graph of a set of graphs S is that graph C which minimizes the sum of Hamming distances between C and G in S. As such, it turns out (for the dichotomous case, at least), to be analogous to both the mean and median for sets of graphs. The central graph is useful in a variety of contexts; see the references below for more details.
由中央的一组曲线图的曲线图小号的是,曲线图,C的最小化S中的C和G之间的汉明距离的总和,因此,事实证明,满分(为二分的情况下,至少),类似于两个平均值的中位数套图。中央图在各种情况下是有用的,有关详细信息,请参阅下面的参考资料。
值----------Value----------
A matrix containing the central graph (or mean matrix)
包含中央图(或平均矩阵的矩阵)
注意----------Note----------
0.5 is used as the cutoff value regardless of whether or not the data is dichotomous (as is tacitly assumed). The routine is unaffected by data type when normalize==TRUE.
使用0.5作为截止值的数据是否是二分(作为默认假定)无关。该例程是不受数据类型时normalize==TRUE。

实例----------Examples----------
#Generate some random graphs[随机生成一些图表]
dat<-rgraph(10,5)
#Find the central graph[中央图]
cg<-centralgraph(dat)
#Plot the central graph[绘制中央图]
gplot(cg)
#Now, look at the mean matrix[现在,看看均值矩阵]
cg<-centralgraph(dat,normalize=TRUE)
print(cg)
