I was running this in RStudio and it gave me this error. I saw that the errors were not being handled in github anymore, so I am posting it here.
Warning message:
The `size` argument of `element_line()` is deprecated as of ggplot2 3.4.0.
Please use the `linewidth` argument instead.
The deprecated feature was likely used in the Maaslin2 package.
Please report the issue at https://github.com/biobakery/maaslin2/issues.
