Diverging palette
This is the ‘PuOr’ palette from https://colorbrewer2.org/. It has at most eleven colors.
diverging_pal(n)
n |
The number of colors in the palette. The maximum is eleven currently. |
This is similar to sequential_pal, but it also puts
emphasis on the mid-range values, plus the the two extreme ends.
Use this palette, if you have such a quantity to mark with vertex
colors.
A character vector of RGB color codes.
Other palettes:
categorical_pal(),
r_pal(),
sequential_pal()

set_vertex_attr("label", value = seq_len(gorder(.))) %>%
set_vertex_attr("size", value = 10) %>%
set_edge_attr("arrow.size", value = 0.3)
V(fw)$color <- scales::dscale(V(fw)$Biomass %>% cut(10), diverging_pal)
plot(fw)
