Thank you for the bug report!

It also crashes on our Solaris platform, and with the newest "developers"
version.  
However, *only* when no device has been created previously in the current R
session, i.e., PREpending 

	par("usr") ; dev.off()

to your three commands gives the correct error message
  >>> Error in par(args) : parameter "tck" has the wrong length

Remark / Question :

 I think I would rather not have my students use low-level functions such
 as   plot.new()  and  plot.window()...

 Is there a reason they need these instead of  plot()/lines()/.... etc ?
