Thanks a million Uwe.
I used the following from a forum to do it and it worked out:
mylevels <-c(-150,-100,-50,-20,-10,-5,-2,-1,1,2,5,10,20,50,100,150)
cols <- jet.colors(length(mylevels) - 1)
customAxis <- function() {
n <- length(mylevels)
y <- seq(min(mylevels), max(mylevels), length.out=n)
rect(0, y[1:(n-1)], 1, y[2:n], col=cols)
axis(4, at=y, labels=mylevels)
}
Many thanks,
Emily

Dear All,
I have a query about using log scales for filled.contour plots. I have
used log values on the x and y axes but labelled the axes with their
linear (non-log) values. I's like to do the same with the contour
values. I want the range to go from -100% to +100%. To use log I just
added 1000 to the % values before taking the log. I'd like the original
% values to appear on the contour lines and in the contour colourbar
labelling.
One way would be to keep the original scale and set explicit breaks
for the levels of contour lines as needed.
Best,
Uwe Ligges
I'd appreciate any suggestions you have.
Many thanks,
Emily Gleeson
