Hi,

I need some help/suggestion how to colour individual nodes in a graph. I've defined the interacting node pairs inside “graph.txt”. Sample data in graph.txt is shown below.

6000184 6005981

6000184 6022212

6000184 6032245

There is other file which contains the 11 colour code based on types of node. The sample file colour.txt looks like

6000184 green

6005981 orange

6022212 orange

6032245 orange

[...]

Hi,

I would do this:

g <- read.graph("graph.txt", format="ncol")
col <- read.table("colour.txt")
V(g)[ match( col[,1], V(g)$name )-1 ]$color <- as.character(col[,2])
print(g, v=T)

Best,
Gabor
