This should work ;
nAttrs<-list()
nAttrs$color <- c(a = "blue", b = "blue", c = "red", d = "red")
plot(g1, nodeAttrs = nAttrs)
see also getDefaultAttrs()
to get all the graph attributes with default values.
Question
I'm using graphNEL
objects from gRbase
and Rgraphviz
for plotting and would like to color the nodes of the graph in different (specified) colors when plotting. For example, how could I plot this graph with a
and b
in blue and c
and d
in red?
library(Rgraphviz)
library(gRbase)
mygraph = dag(~a:c + b:c + b:d)
plot(mygraph)
Solution
This should work ;
nAttrs<-list()
nAttrs$color <- c(a = "blue", b = "blue", c = "red", d = "red")
plot(g1, nodeAttrs = nAttrs)
see also getDefaultAttrs()
