[R] xyplot: adjusting the scale (min, max & tick)

[Jay]

Perfect, that piece of code did exactly what I wanted. However, I stumpled
upon a new problem, now my data is plotted on a totally wrong scale. The
y-values are all between 160k and 500k, BUT now with that option I find that
the plots are between 0 and 50 (?!?). What did I do wrong?

This plots the data OK, even thoug it should be between  160k and 500k on
the y-scale:

xyplot(data1[,2]+data1[,3]~data1[,1], data = data1,
        type = "l",
        xlab = "x",
        ylab = "y",
        auto.key = list(space="top", lines = T, points = F, text=c("text1",
text2")),
        par.settings = simpleTheme(lty = c(1,2)),
        scales=list(
          x=list(alternating=FALSE,tick.number = 11),
          y=list(limits=c(0,50))
        )     
        )   

If I remove the " y=list(limits=c(0,50))" the dat is plotted as it should.
