Launch Shiny app for retrieval of documents from text collection — run_document

This function will be removed in a future version of corporexplorer.

run_document_extractor(corpus_object, max_html_docs = 400, ...)

Arguments

corpus_object: A corporaexplorer object created by prepare_data.
max_html_docs: The maximum number of documents allowed in one HTML report.
...: Other arguments passed to runApp in the Shiny package.

Details

Shiny app for simple retrieval/extraction of documents from a "corporaexplorerobject" in a reading-friendly format. Interrupt R to stop the application (usually by pressing Ctrl+C or Esc).

Examples

# Constructing test data frame:
dates <- as.Date(paste(2011:2020, 1:10, 21:30, sep = "-"))
texts <- paste0(
  "This is a document about ", month.name[1:10], ". ",
  "This is not a document about ", rev(month.name[1:10]), "."
)
titles <- paste("Text", 1:10)
test_df <- tibble::tibble(Date = dates, Text = texts, Title = titles)

# Converting to corporaexplorer object:
corpus <- prepare_data(test_df, corpus_name = "Test corpus")
#> Starting.
#> Document data frame done.
#> Calendar data frame done.
#> Document term matrix: text processed.
#> Document term matrix: tokenising completed.
#> Document term matrix: word list created.
#> Document term matrix done.
#> Done.
