Details

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).

if(interactive()){
face.refresh <- function(...){
	vals <- sapply(1:15, function(x) slider(no=x))
