| sliderv {TeachingDemos} | R Documentation |
Create a Tk slider window with the sliders positioned vertically instead of horizontally.
sliderv(refresh.code, names, minima, maxima, resolutions, starts, title = "control", no = 0, set.no.value = 0)
refresh.code |
Function to be called when sliders are moved. |
names |
Labels for the sliders. |
minima |
Vector of minimum values for the sliders. |
maxima |
Vector of maximum values for the sliders. |
resolutions |
Vector of resolutions for the sliders. |
starts |
Vector of starting values for the sliders. |
title |
Title to put at the top of the Tk box. |
no |
The number of the slider whose value you want. |
set.no.value |
Vector of length 2 with the number of slider to set and the new value. |
This is a variation on the slider function with vertical sliders
arranged in a row rather than horizontal sliders arranged in a column.
This is based on an early version of slider and therefore does
not have as many bells and whistles (but sometimes fits the screen better).
Returns the value of a given slider when used as: slider(no=i).
You can move the slider in 3 different ways: You can left click and drag the slider itself, you can left click in the trough to either side of the slider and the slider will move 1 unit in the direction you clicked, or you can right click in the trough and the slider will jump to the location you clicked at.
