网络图中定义的颜色

Question

我正在使用R来绘制网络图。交互矩阵看起来

>mat
    9   401 562 68  71  569 700
9   0   1   0   0   0   0    1
401 0   0   1   0   0   na   1
562 0   1   0   1   1   0    1 
68  1   1   0   0   0   0    1
71  1   na  0   0   na  0    1
569 1   1   0   1   0   0    0
700 0   0   0    0   0  0    0

>DT_mat<-mat%>%
 as.data.table(keep.rownames=TRUE) %>% 
 melt(id.vars = "rn", value.name="interaction")
>setnames(DT_mat, c("rn", "variable"),  c("source", "target"))

相同交互矩阵的ID的元数据

    >meta
compart group family  genus color.group  color.compart
9    Ex     Prt   A       Ps #EF5656      #2BB065
401  Ex     Prt   A       Ps #EF5656      #2BB065  
562  Ex     Fir   B       Rh #F7A415      #2BB065 
68   In     Fir   C       En #F7A415      #EECF17
71   In     Act   D       Stp #47B3DA     #EECF17  
569  In     Act   D       Stp #47B3DA     #EECF17
700  Ex     Act   E       Aqua #47B3DA    #2BB065

>DT_meta <- as.data.table(meta, keep.rownames=TRUE)
>setkey(DT_meta, rn)
>DT_mat[, paste0(names(DT_meta), ".rows") :=  DT_meta[.(rn.rows)]]

1 - 是否可以使用qgraph（）定义颜色？

> ig_mat <- graph.data.frame(DT_mat, directed=T)
> V(mat)$color <- ifelse(V(mat)$compart=="Ex","#EF5656","#47B3DA")

2 - 当有两种以上的颜色和使用efelse重复卵形时，是否可以使用igraph.plot定义颜色？
