Arguments

label

Label for the current page (character scalar).

prompt

Prompt to be displayed above the response choices. Can be either a character scalar (e.g. "What is 2 + 2?") or an object of class "shiny.tag", e.g. shiny::tags$p("What is 2 + 2?").

choices

Character vector of choices for the participant. If unnamed, then these values will be used both for button IDs and for button labels. If named, then values will be used for button IDs and names will be used for button labels.

labels

Optional vector of labels for the NAFC choices. If not NULL, will overwrite the names of choices. This vector of labels can either be a character vector or a list of Shiny tag objects, e.g. as created by shiny::HTML().

save_answer

Whether or not to save the answer.

arrange_vertically

Whether to arrange the response buttons vertically (the default) as opposed to horizontally.

hide_response_ui

Whether to begin with the response interface hidden (it can be subsequently made visible through Javascript, using the element ID as set in response_ui_id. See audio_NAFC_page for an example.).

response_ui_id

HTML ID for the response user interface.

on_complete

Optional function to execute on leaving the page (after successful validation). The argument list should include ..., and any of: state, the participant's state object; answer, the participant's most recent answer; input, the current page's Shiny input object; session, the current Shiny session object; opt, the test's option list as created by test_options().

admin_ui

Optional UI component for the admin panel.

button_style

Button CSS style information (character scalar).
