Verify the integrity of the column info object

Description

Verify the integrity of the column info object

Usage

verify_column_info(column_info, data)

Arguments

column_info

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.

data

A data frame with items by row and features in the columns. Must contain one column named "id".

Value

The column info object with all expected columns.

Examples

library(tibble)
data <- tribble(
  ~id, ~name, ~x, ~y,
  "foo", "Foo", 0.5, 0.7,
  "bar", "Bar", 1.0, 0.1
)
column_info <- tribble(
  ~id, ~geom,
  "name", "text",
  "x", "funkyrect",
  "y", "funkyrect"
)
verify_column_info(column_info, data)
