Bug description

I download "ggpattern" with the command remotes::install_github("coolbutuseless/ggpattern") ,and download the package successfully.But I run the code in example failed.

library("ggplot2")
library("ggpattern")
df <- data.frame(level = c("a", "b", "c", 'd'), outcome = c(2.3, 1.9, 3.2, 1))

ggplot(df) +
  geom_col_pattern(
    aes(level, outcome, pattern_fill = level), 
    pattern = 'stripe',
    fill    = 'white',
    colour  = 'black'
  ) +
  theme_bw(18) +
  theme(legend.position = 'none') + 
  labs(
    title    = "ggpattern::geom_col_pattern()",
    subtitle = "pattern = 'stripe'"
  ) +
  coord_fixed(ratio = 1/2)

Session info The output in RStudio are following: Error: when calculate 'units' in loadNamespace().onLoad failed，details： call: NULL error: no database found!

Can you tell me how to solve the problem?

• You code example works for me (when tweaked to remove the extraneous markdown and missing library() calls)
• Does library("units") work for you? {units} is a package I think {ggplot2} depends on? Maybe your installation is messed up? If so this isn't something I could help you with.
• You could provide your sessionInfo() output but since this seems unlikely to be a bug in {ggpattern} itself I'm closing the issue for now. Note the error message you see isn't being thrown by {ggpattern} itself but something lower-level. If you set options(error=recover()) you may be able to see where and what is throwing the error...
