  n_scenario = 1,
  colors = c("#f251fc", "#f8ff1b")
)

Value

Examples

# Rename relevant column to page_notes in the derivative document
comment_example_rename <- dplyr::rename(comment_example, page_notes=Notes)
# Tokenize the derivative document
toks_comment <- token_comments(comment_example_rename)
# Rename relevant column in the source document to text
transcript_example_rename <- dplyr::rename(transcript_example, text=Text)
# Tokenize source document
toks_transcript <- token_transcript(transcript_example_rename)
# Compute collocation frequencies
collocation_object <- collocate_comments(toks_transcript, toks_comment)
# Merge frequencies with source document to provide averages by word and correct formatting
merged_frequency <- transcript_frequency(transcript_example_rename, collocation_object)
# Create a plot object to assign colors based on frequency
freq_plot <- collocation_plot(merged_frequency)
