Have a look at the 'scales' argument. For example:
# default plot
xyplot(Sepal.Length ~ Petal.Length | Species, data = iris)
# modified plot
xyplot(Sepal.Length ~ Petal.Length | Species, data = iris,
scales=list(y=list(at=c(-5,0,5,10), limits=c(-5,10))))

Hi,
I'm terribly sorry but it seems it cannot figure this one out by
myself so, please, if somebody could help I would be very grateful.
So, when I plot with xyplot() I get an y-axis that is very ugly...
starting from a random number and having so many ticks that it becomes
unreadable.
How do I tell xyplot how to draw the axis? E.g., start from 100, end
at 200 with 25 units between ticks/labels?
Can somebody give me an example?
Thanks!
