number_trio {switchboard}

Display the value of three continuous variables in a simulation.

Description

The number_trio widget displays the numerical value of three continuous variables.

Arguments

eavesdrop

A vector of three variables to track.

digits

The number of digits to display in a widget.

label

A vector of three small captions/labels for the widget.

updates

The number of times the widget is to be updated (e.g., when it be modified/changed). The default updates with each iteration.

size

A number used to designate the size (magnification) of the widget. The default is set to 1 which is 80 by 80 pixels. For example, setting to 3 will results in a widget 3-times the default size (240 by 240 pixels) and will occupy a grid area of 3 by 3.

placeOnGrid

A row by column coordinate (e.g., c(row-number, column-number)) of a grid that designates the position to draw the widget on the switchboard. Use showGrid() to help organize widget placement on dashboard. The default places the first widget in pipe chain to the c(1, 1) position, and all following on the same row stacked to the right.

Value

Nothing.

Usage

number_trio(eavesdrop = c(NULL, NULL, NULL), digits = 5,
   updates = 1, label = c("", "", ""), size = 1, placeOnGrid = c(1, 1))
