Colleagues

Thanks very much for advice. I was not aware of the Fields package 
(although I've been using Geostat and Spatial). The image.plot() 
function in Fields does a lovely job, with an added bonus of fixing the 
problem I was having of balancing the number of colour levels with the 
xlim parameters.

  image.plot(time.h, z, -log10(t5),
         xlab='hours', ylab='depth m',
         col=topo.colors(64), nlevel=32,
         main = 'Chatham Rise DVM 12 kHz',
         yaxt='n',
         zlim=c(1,8),
         cex=0.5)

R and the community of users and developers certainly provide a splendid 
tool.

Sam
