Fwd: Re: 3d scatter plot with drop line
Hi
try this:
p3dpairs <- function(x,x1,
xlim=NULL,ylim=NULL,zlim=NULL,col=par("col"), pch=par("pch"),
cex=par("cex"), ...){
if(is.matrix(x)){
z <- x[,3]
y <- x[,2]
x <- x[,1]
}
if(is.matrix(x1)){
z1 <- x1[,3]
y1 <- x1[,2]

Arrow and text on a 3d plot
I am currently working on surface plots (with R 2.0.1) and I want to
improve the aspect of them. Having a typical 'cow-boy hat' surface
[source: Spector (1994), p. 206]:
pts <- seq(from = -8, to = 8, length = 50)
cow <- function(x, y)
{
z <- sqrt(x^2+y^2)
sin(z)/z
}
out <- outer(pts, pts, cow)
sur <- persp(x=pts, y=pts, z=out, theta=45, phi=30)
What I exactly wanted is:

3d scatter plot with drop line
This is a follow up to my question from yesterday. I want to do in R
what is called a "3d scatter plot with drop lines" in S-PLUS.
Basically, it's a 3dscatterplot with lines connecting the x-y grid to
the z points.
The lines give a better perspective on the shape of the data surface.
How to?
