[R] get ylim of current plot()

[William Valdar]

Dear All,

How can I query the parameters of the current plot if it was produced by 
plot()? For example, if I do not specify ylim explicitly, eg,

  plot(rnorm(100), rnorm(100))

then how do find out what ylim was chosen? Note that I realize this is 
possible with lattice's xyplot():

  (obj <- xyplot(rnorm(100), rnorm(100)))
  print(obj$y.limits)

Thanks in advance,

Will
