Hi Deepankar
The code on the following page looks kind of cool, and also seems to
produce something of the type of graph you are after perhaps:
https://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/rgl/demo/regression.r?rev=702&root=rgl&sortby=date&view=auto
[below is a copy of the code...
actually, I just realised you also want a line in the plot. I am not
super-sure how to do this.

the following should work
library(lattice)
x <- seq(1,100)
y <- seq(1,100)
gr <- expand.grid(x,y)
gr$z <- x + y + rnorm(1,0,100)
cloud(z ~ x + y, data = gr)
also, look for the package rgl which does similar but with more
possiblities.

Hi R Users,
I have produced a simulated scatter plot of y versus x tightly clustered
around the 45 degree line through the origin with the following code:
x <- seq(1,100)
y <- x+rnorm(100,0,10)
plot(x,y,col="blue")
abline(0,1)
Is there some way to generate a 3-dimensional analogue of this? C
