我有两个问题,第一个比第二个更复杂。使用igraph在R中绘制比较大的网络
我有一个我的网络下面的情节,但剧情是聚集在一起,我怎么能扩散节点出更多,所以我可以清楚地看到边缘。我试过了一个圆形的情节,但我仍然有一个相当集群的情节。
如何重命名节点?当前的图表在节点名称的前面放置了一个“X”,我该如何删除'X'?
以我基质的相互作用节点标有1
,非相互作用的节点都标有0
代码:
library(igraph)
df <- as.matrix(read.table("sig_pairs_matrix_for_r.txt"))
g=graph.adjacency(df,mode="undirected",weighted=NULL,diag=FALSE)
plot.igraph(g,vertex.label=V(g)$name)
矩阵:
4 6 7 8 12 13 15 17 22 23 25 26 27 29 30 31 34 35 36 43 44 47 48 52 53 56 57 59 63 66 67 70 96 99 122 166 168 172 174 176 180 181 191 192 193 220 222 224 225 226 236 249 253 256 258 266 267 277 296

如果您可以使您的数据以更贴近“R-friendly-friendly”的方式提供,这将有所帮助。你可以使用'dput'来做到这一点。 – 2013-03-10 09:54:11
