Set up graphical options for graphs

This function sets up graphical options for igraph objects. Existing options include:

vimes_graph_opt(...)

Arguments

...

a list of named graphical options; see Description.

Details

• col_pal a color palette used for the groups; defaults to vimes_pal1

• layout a layout function used for plotting the graph; see ?layout_nicely for more information.

• seed a random seed to be used for plotting the graph

• vertex_size the size of the vertices; defaults to 10

• label_family a font family for labels; defaults to "sans"

• label_color the color of the labels; defaults to "black"

• edge_label a logical indicating if weights should be used to annotate the edges; defaults to FALSE
