[Rd] Probable bug in "An Introduction to R" (PR#10777)

[lefevrol at yahoo.com]

Both the document and R itself are at 2.6.2 (2008-02-08). When I run in 
the Windows R console the command 

   lines(density(eruptions, bw=0.1))

found in § 8.2, I get:

   Error in plot.xy(xy.coords(x, y), type = type, ...) : 
   plot.new has not been called yet
