Project hapax legomena onto vocabulary growth

plot_hapax() visualizes a sampling of hapax legomena projected on faceted curves of vocabulary growth over time

Usage

plot_hapax(
  data,
  prop = 0.01,
  x = progress,
  y = vocabulary,
  by = doc_id,
  descriptive_labels = TRUE,
  feature = hapax_doc
)

Arguments

data

A tidy data frame, potentially containing columns called "doc_id" and "word"

prop

The proportion of hapax to sample. The chart can become illegible with proportions over ~1%

x

A column showing the cumulative progress of documents

y

The Y-axis variable to chart. Default value is the cumulative vocabulary size.

by

A grouping column, such as doc_id

descriptive_labels

A toggle for disabling descriptive labels of progress_percent on the X-axis

feature

The column to check for new features. Defaults to hapax_doc, but the function might also be used with new_word instead to plot a sample of new additions to documents' vocabularies.

Value

A ggplot object
