Highlight Conserved Edits Across Versions of a Document.

highlightr

This package can be used to create a highlighted source document based on the frequency of phrases found in single or multiple note sheets. The goal of this method is to indicate the portions of the source document that individuals felt was most worth copying into notes, based on phrase frequency. The inputs necessary for this procedure are a notes document and a source document. The output will be HTML code for generating the highlighted text.

comment_example_rename <- dplyr::rename(comment_example, page_notes=Notes)
toks_comment <- token_comments(comment_example_rename)
transcript_example_rename <- dplyr::rename(transcript_example, text=Text)
toks_transcript <- token_transcript(transcript_example_rename)
collocation_object <- collocate_comments_fuzzy(toks_transcript, toks_comment)
merged_frequency <- transcript_frequency(transcript_example_rename, collocation_object)
freq_plot <- collocation_plot(merged_frequency)
page_highlight <- highlighted_text(freq_plot)
