checkboxGroupInput: Checkbox Group Input Control

In ymd526442121/Rproject_shiny: Web Application Framework for R

Description

Create a group of checkboxes that can be used to toggle multiple choices independently. The server will receive the input as a character vector of the selected values.

Usage

checkboxGroupInput(inputId, label, choices, selected = NULL, inline = FALSE,
  width = NULL)

Arguments

inputId	The input slot that will be used to access the value.
label	Display label for the control, or NULL for no label.
choices	List of values to show checkboxes for. If elements of the list are named then that name rather than the value is displayed to the user.
selected	The values that should be initially selected, if any.
inline	If TRUE, render the choices inline (i.e. horizontally)
width	The width of the input, e.g. '400px', or '100%'; see validateCssUnit.

Value

A list of HTML elements that can be added to a UI definition.
