In ggplot2: Create Elegant Data Visualisations Using the Grammar of Graphics

layer() checks its input

Can't create layer without a geom.

Can't create layer without a stat.

Can't create layer without a position.

`mapping` must be created by `aes()`

`mapping` must be created by `aes()`
i Did you use `%>%` or `|>` instead of `+`?

Can't find geom called "test"

`x` must be either a string or a <geom> object, not an environment.

invalid aesthetics throws errors

Problem while computing aesthetics.
i Error occurred in the 1st layer.
Caused by error in `compute_aesthetics()`:
! Aesthetics are not valid data columns.
x The following aesthetics are invalid:
x `fill = data`
i Did you mistype the name of a data column or forget to add `after_stat()`?

Problem while mapping stat to aesthetics.
i Error occurred in the 1st layer.
Caused by error in `map_statistic()`:
! Aesthetics must be valid computed stats.
x The following aesthetics are invalid:
x `fill = after_stat(data)`
i Did you map your stat in the wrong layer?

function aesthetics are wrapped with after_stat()

Problem while computing aesthetics.
i Error occurred in the 1st layer.
Caused by error in `compute_aesthetics()`:
! Aesthetics are not valid data columns.
x The following aesthetics are invalid:
x `colour = NULL`
x `fill = NULL`
i Did you mistype the name of a data column or forget to add `after_stat()`?

computed stats are in appropriate layer

Problem while mapping stat to aesthetics.
i Error occurred in the 1st layer.
Caused by error in `map_statistic()`:
! Aesthetics must be valid computed stats.
x The following aesthetics are invalid:
x `colour = NULL`
x `fill = NULL`
i Did you map your stat in the wrong layer?

layer reports the error with correct index etc

Problem while setting up geom.
i Error occurred in the 1st layer.
Caused by error in `compute_geom_1()`:
! `geom_linerange()` requires the following missing aesthetics: ymax or xmin and xmax

Problem while converting geom to grob.
i Error occurred in the 2nd layer.
Caused by error in `draw_group()`:
! Can only draw one boxplot per group
i Did you forget `aes(group = ...)`?

layer_data returns a data.frame

`layer_data()` must return a <data.frame>
