The `ggseg_atlas` class is a subclass of [`data.frame`][data.frame()], created in order to have different default behaviour. It heavily relies on the "tibble" [`tbl_df`][tibble()]. [tidyverse](https://www.tidyverse.org/packages/), including [dplyr](http://dplyr.tidyverse.org/), [ggplot2](http://ggplot2.tidyverse.org/), [tidyr](http://tidyr.tidyverse.org/), and [readr](http://readr.tidyverse.org/).

Objects of class `ggseg_atlas` have: * A `class` attribute of `c("ggseg_atlas", "tbl_df", "tbl", "data.frame")`. * A base type of `"list"`, where each element of the list has the same [NROW()]. * A lot of this script and its functions are taken from the [`tibble`][tibble()]-package
