Igraph in R : how to change edge color based on edge attribute. Ask Question Asked 4 years, 7 months ago. Active 3 years, 4 months ago. Viewed 5k times 2. 1. I am trying to generate an Igraph in R . Now I want the edge color dependent on an edge attribute – department. I cannot use ifelse statement because department values can be dynamic.
The color of the labels, see the color vertex parameter discussed earlier for the possible values. The default value is black. Edge parameters require to add the ‘ edge .’ prefix when used as arguments or set by igraph _options. The edge parameters: color . The color of the edges , see the color vertex parameter for the possible values.
Details. edges is an alias for edge .. When adding edges via +, all unnamed arguments of edge (or edges ) are concatenated, and then passed to add_ edges .They are interpreted as pairs of vertex ids, and an edge will added between each pair. Named arguments will be used as edge attributes for the new edges .
Details. When adding edges via +, all unnamed arguments are concatenated, and each element of a final vector is interpreted as a vertex in the graph.For a vector of length n+1, n edges are then added, from vertex 1 to vertex 2, from vertex 2 to vertex 3, etc. Named arguments will be used as edge attributes for the new edges .. When deleting edges , all attributes are.
First, as I noted in the comments, as you constructed it, realfriend is a property of the edges , not the vertices. To be able to color the vertices, you need a property of the vertices. … Weighted edges in R / igraph . 5. Graph.union summing edge weights attributes ( igraph R ) 3. Color by degree in R using ggnet2. 0.
