I tried drawing with sample code and sample data. The package was libraried without errors or warnings.

library(ggplot2)
library(gggenes)

ggplot(example_genes, aes(xmin = start, xmax = end, y = molecule, fill = gene)) +
    geom_gene_arrow() +
    facet_wrap(~ molecule, scales = "free", ncol = 1) +
    scale_fill_brewer(palette = "Set3")

But something went wrong unexpectedly.

Error in grid.Call(C_convert, x, as.integer(whatfrom), as.integer(whatto),  : 
  Viewport has zero dimension(s)

There's nothing wrong with the data.

> head(example_genes)
  molecule gene start   end  strand orientation
1  Genome1 genA 15389 17299 reverse           1
2  Genome1 genB 17301 18161 forward           0
3  Genome1 genC 18176 18640 reverse           1
4  Genome1 genD 18641 18985 forward           0
5  Genome1 genE 18999 20078 reverse           1
6  Genome1 genF 20086 20451 forward           1

Can anyone help me explain why?
