Fuzzily Search Help and View the Selection

Users no more have to afraid of exact name of the object they need help. A shiny gadget helps you to find a topic fuzzily. Click radio buttons to switch preview contents. Click "Done" or "Cancel" to close the widget. The "Done" button will also hook help function on the selection.

fuzzyhelp(
  query = "",
  method = getOption("fuzzyhelp.method", "fzf"),
  background = getOption("fuzzyhelp.background", TRUE)
)

Arguments

query: An initial query to search for the help system.
method: A fuzzy match method to use. Choices are "fzf" and "lv" (levenstein). The method "lv" is faster but can be less accurate. The default value can be tweaked by options(fuzzyhelp.method = "lv").
background: Whether to run a shiny gadget in a background process. The default value is TRUE and can be changed by option(fuzzyhelp.background = FALSE).

Note

The default fuzzy match algorithm is a simplified version of https://github.com/junegunn/fzf. The implementation in this package excludes bonuses from relationship with matched characters and their previous characters.

Examples

if (FALSE) {
  fuzzyhelp()
}
