ISwR Plotting Issue

I'm trying to replicate the linear regression plot on pages 112-113 in
Peter Dalgaard's "Introductory Statistics with R" and getting the error that
"plot.new has not been called yet."

   A Web search on that error offered suggestions to run plot.new() or x11(),
but all those do is put up an empty plotting window. My code, and R's
responses, follow:
Attaching package: ?ISwR?

The following object is masked from ?package:survival?:

     lung
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
   plot.new has not been called yet

  What have I missed here?

Answer: keeping the plot window open when issuing the abline() command.

Rich,

I loaded ISwR and ran your code (as cut-n-paste from your email) and got a plot of the data with regression line without any error message.  What version of R and ISwR are you running?  Have you tried closing R and starting a clean session?   

Since the example worked for me, there is not much else I can help with.
