In shinyGovstyle: Custom Gov Style Inputs for Shiny

Radio Button Function

Description

This function create radio buttons

Usage

radio_button_Input(
  inputId,
  label,
  choices = NULL,
  selected = NULL,
  inline = FALSE,
  small = FALSE,
  choiceNames = NULL,
  choiceValues = NULL,
  hint_label = NULL,
  error = FALSE,
  error_message = NULL,
  custom_class = ""
)

Arguments

inputId	The input slot that will be used to access the value
label	Input label
choices	List of values to select from (if elements of the list are named then that name rather than the value is displayed to the user)
selected	The initially selected value.
inline	If you want the radio inline or not, Default is FALSE
small	If you want the smaller versions of radio buttons, Default is FALSE
choiceNames, choiceValues	Same as in shiny::checkboxGroupInput(). List of names and values, respectively, that are displayed to the user in the app and correspond to the each choice (for this reason they must have the same length). If either of these arguments is provided, then the other must be provided and choices must not be provided. The advantage of using both of these over a named list for choices is that choiceNames allows any type of UI object to be passed through (tag objects, icons, HTML code, ...), instead of just simple text
hint_label	Additional hint text you may want to display below the label. Defaults to NULL
error	Whenever you want to include error handle on the component
error_message	If you want a default error message
custom_class	If you want to add additional classes to the radio buttons

Value

radio buttons HTML shiny tag object
