This is how I did for a circus plot: `annotate.node_labels(G, group_by="group", sort_by = "value", layout_func = layouts.circos)` 

A quick check is to run your R studio as administrator; OR: try the unzip method using this link: https://jtr13.github.io/cc21fall2/tutorial-of-radar-chart.html (You need to run the cmd as administrator as well)
