我有一个网络,当我绘制它时,有许多重叠的节点.我想更改颜色的不透明度,以便在重叠时可以看到其他节点.例如,请参阅此视频:https://vimeo.com/52390053
我正在使用iGraph我的情节.这是一个简化的代码模糊:
net1 <- graph.data.frame(myedgelist, vertices=nodeslist, directed = TRUE)
g <- graph.adjacency(get.adjacency(net1))
V(g)$color <- nodeslist$colors #This is a set of specific colors corresponding to each node. They are in the format "skyblue3". (These plot correctly for me).
E(g)$color <-"gray"
plot.igraph(g)
但是,我无法找到iGraph更改节点颜色不透明度的选项.
知道怎么做这个吗？我想也许是这样的V(g)$alpha <- 0.8,但这没有做任何事情.
