Package examples fail with: `Error in set_class(., "gggenomes_layout", "prepend")`

[iferres]

Hi, I'm having an issue with the package with examples failing:

library(gggenomes)

# to inspect the example data shipped with gggenomes
data(package="gggenomes")

gggenomes(emale_genes, emale_seqs, emale_tirs, emale_ava) %>%
  add_feats(ngaros=emale_ngaros, gc=emale_gc) %>%
  add_sublinks(emale_prot_ava) %>%
  flip_by_links() +
  geom_feat(position="identity", size=6) +
  geom_seq() +
  geom_link(data=links(2)) +
  geom_bin_label() +
  geom_gene(aes(fill=name)) +
  geom_gene_tag(aes(label=name), nudge_y=0.1, check_overlap = TRUE) +
  geom_feat(data=feats(ngaros), alpha=.3, size=10, position="identity") +
  geom_feat_note(aes(label="Ngaro-transposon"), feats(ngaros),
      nudge_y=.1, vjust=0) +
  geom_ribbon(aes(x=(x+xend)/2, ymax=y+.24, ymin=y+.38-(.4*score),
      group=seq_id, linetype="GC-content"), feats(gc),
      fill="lavenderblush4", position=position_nudge(y=-.1)) +
  scale_fill_brewer("Genes", palette="Dark2", na.value="cornsilk3")

## Error in set_class(., "gggenomes_layout", "prepend") : 
##  3 arguments passed to 'class<-' which requires 2

This error is minimally reproduced as follows:

gggenomes(emale_genes, emale_seqs, emale_tirs, emale_ava)

## Error in set_class(., "gggenomes_layout", "prepend") : 
##  3 arguments passed to 'class<-' which requires 2

Great package btw, thanks!

Nevermind, I just updated ggplot2 and now it works. Sorry!

No problem! I like issues that solve themselves ;)
