Run a web interface allowing basic word frequency analysis

Usage

cas_explorer(
  corpus = NULL,
  default_pattern = NULL,
  title = "castarter",
  collect = FALSE,
  advanced = FALSE,
  custom_head_html = "<meta name=\"referrer\" content=\"no-referrer\" />",
  footer_html = shiny::tagList(),
  onStart = NULL,
  options = list(),
  enableBookmarking = NULL,
  uiPattern = "/",
  ...
)

Arguments

corpus: Defaults to NULL. If not given, by default the main table with extracted contents will tentatively be retrieved with cas_read_db_contents_data(). Consider that for improved speed and reduced memory requirements it may be more efficient to store locally the corpus (e.g. with cas_write_corpus(partition = "year")), and read it as input to this argument with cas_read_corpus(partition = "year").
collect: Defaults to FALSE. If TRUE, retrieves the corpus in memory, even if is originally read from a parquet file or a database. With arrow version before 14 that do not have full support of using stringr in context, setting this to TRUE is probably advisable (currently, depending on the arrow version, there may be issues where upper/lower case is not ignored).
custom_head_html: Chunk of code to be included in the app's <head>. This can be used, e.g., for custom analytics snippets. The default value, <meta name="referrer" content="no-referrer" /> asks the browser not to include the source website when following links to external websites.
onStart: A function that will be called before the app is actually run. This is only needed for shinyAppObj, since in the shinyAppDir case, a global.R file can be used for this purpose.
options: Named options that should be passed to the runApp call (these can be any of the following: "port", "launch.browser", "host", "quiet", "display.mode" and "test.mode"). You can also specify width and height parameters which provide a hint to the embedding environment about the ideal height/width for the app.
enableBookmarking: Can be one of "url", "server", or "disable". The default value, NULL, will respect the setting from any previous calls to enableBookmarking(). See enableBookmarking() for more information on bookmarking your app.
uiPattern: A regular expression that will be applied to each GET request to determine whether the ui should be used to handle the request. Note that the entire request path must match the regular expression in order for the match to be considered successful.
...: arguments to pass to golem_opts. See ?golem::get_golem_options for more details.
