tc_plot_tree

A wrapper for the <code>plot_tree</code> function, that can be used directly on a tCorpus.

Provides text analysis in R, focusing on the use of a tokenized text format. In this format, the positions of tokens are maintained, and each token can be annotated (e.g., part-of-speech tags, dependency relations).
Prominent features include advanced Lucene-like querying for specific tokens or contexts (e.g., documents, sentences),
similarity statistics for words and documents, exporting to DTM for compatibility with many text analysis packages,
and the possibility to reconstruct original text from tokens to facilitate interpretation.

tc_plot_tree function

<dl><dt>tc</dt>
<dd>a tCorpus</dd>
<dt>...</dt>
<dd>Arguments passed to <code>plot_tree</code>. Most importantly, this is used to select which specific columns to display on the bottom rows.
For instance, tc_plot_tree(tc, token, lemma, POS) shows only these three columns.</dd>
<dt>annotation</dt>
<dd>Optionally, the name of a column with an rsyntax annotation.</dd>
<dt>sentence_i</dt>
<dd>By default, plot_tree uses the first sentence (sentence_i = 1) in the data. sentence_i can be changed to select other sentences by position (the i-th unique sentence in the data). Note that sentence_i does not refer to the values in the sentence column (for this use the sentence argument together with doc_id)</dd>
<dt>doc_id</dt>
<dd>Optionally, the document id can be specified. If so, sentence_i refers to the i-th sentence within the given document.</dd>
<dt>pdf_file</dt>
<dd>Directly save the plot as a pdf file</dd></dl>
