Plot polarity scores of words

Usage

textplot_terms(
  x,
  highlighted = NULL,
  max_highlighted = 50,
  max_words = 1000,
  ...
)

x: a fitted textmodel_lss object.
highlighted: quanteda::pattern to select words to highlight. If a quanteda::dictionary is passed, words in the top-level categories are highlighted in different colors.
max_highlighted: the maximum number of words to highlight. When highlighted = NULL, words to highlight are randomly selected proportionally to polarity ^ 2 * log(frequency).
max_words: the maximum number of words to plot. Words are randomly sampled to keep the number below the limit.
...: passed to underlying functions. See the Details.

Users can customize the plots through ..., which is passed to ggplot2::geom_text() and ggrepel::geom_text_repel(). The colors are specified internally but users can override the settings by appending ggplot2::scale_colour_manual() or ggplot2::scale_colour_brewer(). The legend title can also be modified using ggplot2::labs().
