colourpicker (version 0.3)

colourWidget: Create a colour picker htmlwidget

Description

Create a colour picker htmlwidget. This is not terribly useful right now since you can use the more powerful colourInput in Shiny apps and Rmarkdown documents, but this gives you an htmlwidget version of that colour picker.

Usage

colourWidget(value = "white", showColour = c("both", "text", "background"), palette = c("square", "limited"), allowedCols, width = "300px", height = "35px", elementId = NULL)

Arguments

value

Initial value (can be a colour name or HEX code)

showColour

Whether to show the chosen colour as text inside the input, as the background colour of the input, or both (default).

palette

The type of colour palette to allow the user to select colours from. square (default) shows a square colour palette that allows the user to choose any colour, while limited only gives the user a predefined list of colours to choose from.

allowedCols

A list of colours that the user can choose from. Only applicable when palette == "limited". The limited palette uses a default list of 40 colours if allowedCols is not defined.

width

Custom width for the input field.

height

Custom height for the input field.

elementId

Use an explicit element ID for the widget (rather than an automatically generated one).

Examples

colourWidget()
colourWidget("red", palette = "limited", allowedCols = c("yellow", "red", "#123ABC"))
