It is important that the theme be calculated after the package is loaded. If not, a theme object —stored as a variable in the built package— may or may not align with the installed version of ggplot2!

```{r}
default_theme <- function() {
theme_custom()
}

mpg_drv_summary2 <- function() {
mpg_drv_summary() + default_theme()
mpg_drv_summary() + theme_custom()
}
