Works perfectly well with R-2.14.1 32-bit on a Windows device. Since you
have not followed the posting guide and forgot to give details about
your platform, there is not much we can do.

When I use the image() function for a relatively small matrix it works perfectly,
eg.x- 1:100
z- matrix(rnorm(10^4),10^2,10^2)
image(x=x,y=x,z=z,col=rainbow(3))but when I want to plot a larger matrix, it
doesn't really work. Most of the times, it just plot a few intermitent
points.x- 1:1000
z- matrix(rnorm(10^6),10^3,10^3)
image(x=x,y=x,z=z,col=rainbow(3))
Generating the matrix didn't seem to be a problem. I would appreciate any
thoughts and ideas.
I have tried using heatmap in bioconductor. However, I want to substitute the
dendograms with axes, but when I suppressed the dendogram, I can't successfully
add any axis. If anyone knows heatmap() well and would like to help via this
function, it would work also.
