[R] Lattice: how to get default ylim?

[Wladimir Eremeev]

Dear r-help,

  I draw graphics with xyplot and want to add some text to each panel
  (actually, the slope, error and significance of a regression line).

  I have defined the function, drawing a single panel and pass it to
  xyplot in the panel argument. This function calls panel.xyplot,
  calculates linear regression and formats coefficients.

  Now I want the text, I mentioned above, to be put in the upper left
  corner of each plot.
  I use ltext, and I need to define coordinates x and y.
  In order to do this I need to know the limits of x and y axes.

  I do not want to pass arguments xlim and ylim to the xyplot function
  and want it to calculate them automatically.
  And I also want to know the result of calculations. :)
  How to do this?
  
  Thank you very much.
