Dear all,
I'm joining differnts graphs to one with command graph_join from ggraph,
and try to color the nodes depending on the subgraph they come from.
To do that, I have these commands in my ggraph:
####################################################
...
geom_node_point(size = 8, aes(colour = project_all$Acronym)) +
scale_color_discrete(name="Project / Projekt") +
...
####################################################
All works well, but
how to define the colors to use for the nodes?
Is it possible to either
- define the colors explicitely, or
- define a color palette to use?
Please point me to where I should look how to do it.
Many thanks in advance
Wolfgang
