Usage

plot_ngram_frequency(
  ngram_data,
  top_n = 30,
  selected = NULL,
  title = "N-gram Frequency",
  highlight_color = "#10B981",
  default_color = "#6B7280",
  height = 500,
  width = NULL,
  show_stats = TRUE
)

Arguments

• collocation: The n-gram text

• count: Frequency count

• lambda: (optional) Lambda statistic

• z: (optional) Z-score statistic
