Hi,

So I am trying to plot my results of a model. what i have is the majority
of the data between the values of 0 and 30, then one outlier at 80 and
another at 130. the model plots a nice line through the data between 0 to 30, however given the outliers you cant seen this unless you change the y axis using ylim=c(0,30) but then you can only see the data points in this range. What I would like to do is plot a y axis with a multiple scale, so if i have 10 equally spaced ticks, 0 to 8 would be the data between 0 and 30, and then tick 9 would be 80 and tick 10 130, so that the two outliers would be show in the graph. I think what i have seen is a graph with the axis on one scale, then a squiggly line to another scale, and a squiggly
like to a third scale.


I seem to remember a post from Sarkar that there is no provision for broken axes in lattice, so you will perhaps need to stay with base graphics. The places to look for this sort of request are in plotrix and TeachingDemos packages. I seem to remember such a question in the past, so if that isn't immediately effective (actually it was when I just checked so I am leaving it as an exercise for the poster), then do some searching in the archives. And I see you are on posting from Nabble. Nabble is not a particularly good place to do searches. Use Baron's site, or Rseek, or sos::findFn, or Markmail or gmane. They are all bette for searching. You might want to read the Posting Guide too.
