Verify the integrity of the column groups object


verify_column_groups(column_groups, column_info)



A data frame describing of how to group the columns in column_info. Can consist of the following columns:

  • group (character): The corresponding group in column_info$group.

  • palette (character, optional): The palette used to colour the column group backgrounds.

  • level1 (character): The label at the highest level.

  • level2 (character, optional): The label at the middle level.

  • level3 (character, optional): The label at the lowest level (not recommended).


A data frame describing which columns in data to plot. This data frame should contain the following columns:

  • id (character, required): A column name in data to plot. Determines the size of the resulting geoms, and also the color unless color is specified.

  • id_color (character): A column name in data to use for the color of the resulting geoms. If NA, the id column will be used.

  • id_size (character): A column name in data to use for the size of the resulting geoms. If NA, the id column will be used.

  • name (character): A label for the column. If NA or "", no label will be plotted. If this column is missing, id will be used to generate the name column.

  • geom (character): The geom of the column. Must be one of: "funkyrect", "circle", "rect", "bar", "pie", "text" or "image". For "text", the corresponding column in data must be a character. For "pie", the column must be a list of named numeric vectors. For all other geoms, the column must be a numeric.

  • group (character): The grouping id of each column, must match with column_groups$group. If this column is missing or all values are NA, columns are assumed not to be grouped.

  • palette (character): Which palette to colour the geom by. Each value should have a matching value in palettes$palette.

  • width: Custom width for this column (default: 1).

  • overlay: Whether to overlay this column over the previous column. If so, the width of that column will be inherited.

  • legend: Whether or not to add a legend for this column.

  • hjust: Horizontal alignment of the bar, must be between [0,1] (only for geom = "bar").

  • vjust: Vertical alignment of the label, must be between [0,1] (only for geom = "text").

  • size: Size of the label, must be a numeric value (only for geom = "text").

  • label: Which column to use as a label (only for geom = "text").

  • directory: Which directory to use to find the images (only for geom = "image").

  • extension: The extension of the images (only for geom = "image").

  • draw_outline: Whether or not to draw bounding guides (only for geom == "bar"). Default: TRUE.

  • options (list or json): Any of the options above. Any values in this column will be spread across the other columns. This is useful for not having to provide a data frame with 1000s of columns. This column can be a json string.
