Is there a way to add a legend to an image plot? I don't see any
reference to legends in the documentation (so I suppose the answer is
no?). Although the documentation says image takes plot() parameters, it
isn't clear to me how the usual use of legend in a plot command would go
for image(). Perhaps you need to specify 'breaks' and then use something
like:
legend(x,y, breaks, c('label1', label2'...))
?
Here is my function call at the moment without a legend:
image(time.h, z, -log10(t5),
xlab='hours', ylab='depth m',
col=rainbow(20),
main = 'Chatham Rise DVM',
yaxt='n', zlim=c(2,6.5), cex=0.5)
Thanks in advance,
Sam

Check out `image.plot' in the `fields' package. Also, `filled.contour' may do what you want (and seems to produce nicer pictures). -roger _______________________________ UCLA Department of Statistics rpeng at stat.ucla.edu http://www.stat.ucla.edu/~rpeng On Tue, 17 Sep 2002, Sam McClatchie wrote:> System info: > Linux slackware > R Version 1.5.1 (2002-06-17) > ESS 5.1.21 > Emacs 21.2.1 > ------------------- > Colleagues > > Is there a way to add a legend to an image plot?
