How can I color nodes of a graphNEL graph?

graph-visualization, graphviz, r

Solution

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.

Problem

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) ```
