Plot the distribution of a categorical trait by family

For the families with the most taxa scored for a categorical trait, plots the proportion of each family's taxa with each value of the trait. Each taxon counts once: within a dataset, a taxon's distinct values share its weight equally (a value cell such as "simple compound" counts as both values), and its datasets are then combined. Point colour shows that proportion, and point size the number of the family's taxa with any record of the value. Values are ordered from most to least common in the families shown. Ties between families at the family_count cut-off are broken alphabetically.

Usage

plot_categorical_trait_distribution(database, trait_name, family_count = 50)

Arguments

database

traits.build database (list object), or its traits table (which must then have a family column, e.g. from join_taxa())

trait_name

Name of the trait to plot (matched exactly)

family_count

Number of families to show: those with the most taxa scored for the trait

Value

A ggplot object, or a blank plot saying there are no values to plot

Examples

austraits_lite %>% plot_categorical_trait_distribution("leaf_compoundness", family_count = 20)
