R help - Nov 2007 - add histograms or distributions on regression line

hello, does anyone know how to add histograms or distributions
on regression like just like quantiles regression in RGraphGallery
below, a very
delicate codes. Thanks alot.

If you go to the source code area of the page and
click on one of the icons to get the source code for
that graph.  

The code looks a bit complex for me to figure out
quickly , but it may give you a start on how to
approach it.

Here are a couple of options that may get you started:

library(TeachingDemos)

plot(1:10, 1:10, type='n')
abline(0,1)

rhist <- function(x){
	tmp <- hist(x, plot=FALSE)
	barplot(tmp$counts, horiz=TRUE, axes=FALSE, space=0)
}

subplot( rhist(rnorm(100)), 2,2, hadj=0 )
subplot( rhist(rnorm(100)), 5,5, hadj=0 )
subplot( rhist(rnorm(100)), 7,7, hadj=0 )

y <- seq(-3,3, len=100)
x <- dnorm(y)
x <- x/(max(x))
ms.norm <- cbind(x,y)

plot(1:10,1:10, type='n')
abline(0,1)

my.symbols( 1:10, 1:10, ms.norm, inches=0.3 )

plot(1:10,1:10, type='n')
abline(0,1)

my.symbols( 1:10, 1:10, ms.norm, inches=seq(.2,.5,len=10) )



Hope this helps,
