R - draw genes in ggplot2 plots with <em>gggenes</em>

https://cran.r-project.org/web/packages/gggenes/vignettes/introduction-to-gggenes.html

Draw genes in ggplot2 plots with geom_gene_arrow(), geom_gene_label(), and geom_subgene_arrow() geom_subgene_label()

ggplot(subset(example_genes, molecule == "Genome4" & gene == "genA"),
       aes(xmin = start, xmax = end, y = strand)
  ) +
  geom_gene_arrow() +
  geom_gene_label(aes(label = gene)) +
  geom_subgene_arrow(
    data = subset(example_subgenes, molecule == "Genome4" & gene == "genA"),
    aes(xsubmin = from, xsubmax = to, fill = subgene)
  ) +
  geom_subgene_label(
    data = subset(example_subgenes, molecule == "Genome4" & gene == "genA"),
    aes(xsubmin = from, xsubmax = to, label = subgene),
