nothing flipped

p0 <- p %>% add_links(emale_ava)

flip manually

p1 <- p %>% add_links(emale_ava) %>% flip(4:6) + labs(caption="manually")

flip automatically based on genome-genome links

p2 <- p %>% add_links(emale_ava) %>% sync() + labs(caption="genome alignments")

flip automatically based on protein-protein links

p3 <- p %>% add_sublinks(emale_prot_ava) %>% sync() + labs(caption="protein alignments")

flip automatically based on genes linked implicitly by belonging

to the same clusters of orthologs (or any grouping of your choice)

p4 <- p %>% add_clusters(emale_cogs) %>% sync() + labs(caption="shared orthologs")

p0 + p1 + p2 + p3 + p4 + plot_layout(nrow=1, guides="collect")

fancy flipping using tidyselect::where for dynamic selection

p <- gggenomes(emale_genes,emale_seqs) %>% add_clusters(emale_cogs) + geom_seq(color="grey70", size=1, arrow = arrow(angle = 30, length = unit(15, "pt"), ends = "last", type = "open")) + geom_gene(aes(fill=cluster_id))
