summary_metadata.RdFunctions to add or retrieve corpus summary metadata
add_summary_metadata(x, extended = FALSE, ...)
get_summary_metadata(x, ...)
summarize_texts_extended(x, stop_words = stopwords("en"), n = 100)add_summary_metadata() returns a corpus with summary metadata added
as a data.frame, with the top-level list element names summary.
get_summary_metadata() returns the summary metadata as a data.frame.
summarize_texts_extended() returns extended summary information.
This is provided so that a corpus object can be stored with
summary information to avoid having to compute this every time
[summary.corpus()] is called.
So in future calls, if !is.null(meta(x, "summary", type = "system") && !length(list(...)), then summary.corpus() will simply return
get_system_meta() rather than compute the summary statistics on the fly,
which requires tokenizing the text.
