radio_button_Input: 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 = ""
)

Value

radio buttons html shiny object

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 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

  ui <- fluidPage(

      }
