G'day
A quick followup is that it doesn't always happen. I managed to reproduce it
on a fresh start-up
by adding the two lines indicated by arrows
try this:
x<-1:10
y<-sin(x) #yes I know it's an under sampled function
-> plot(x,y) ###These two lines are required to reproduce the
-> lines(x,y) ### behaviour
xyplot(y~x)
lines(x,y) #at this point the lines do not lay on the xypoints
spline(x,y)
points(x,y) # in my installation the points(x,y) do not lay on the xyplot
points
