Hi
I tried to do similar thing and did get great answer from Alberto Monteiro
http://tolstoy.newcastle.edu.au/R/e4/help/08/01/0682.html
However I finally managed to do it by slicing space by combination of
image and contour together with putting numbers on contour. Then I used
scizors and glu
I'm basically put off by the question itself. Plotting a 4-dimensional
graph is rather "complicated" if the world has only 3 dimensions. A
4-dimensional representation is typically a movie (with time as the
4th dimension). You could try to project a heatmap on a 3D surface
graph, but I doubt this w

Thanks for your reply.
But I don't think it will really help. My problem is as follows:
I have 20 observations
y <- rnorm(N,mean= rep(th[1:2],N/2),sd=th[3])
I have a loglikelihood function for 3 variables mu<-(mu1,mu2) and sig
loglike <- function(m
sorry for y
y=rnorm(20,mean= rep(th[1:2],10),sd=th[3])
th=c(0, 0.5, 1)

How about : google "r graph gallery 4d" ?

It will be straightforward to see it if we can graph the d surface
if d is only a function of a and b, I can use 'persp' to see the surface o
Suppose there are 4 variables
