left_right {ggvis} | R Documentation |
Interactive inputs bound to arrow keys.
left_right(min, max, value = (min + max)/2, step = (max - min)/40) up_down(min, max, value = (min + max)/2, step = (max - min)/40)
min |
A minimum value. |
max |
A maximum value. |
value |
The initial value before any keys are pressed. Defaults to
half-way between |
step |
How much each key press changes |
