You haven't told us the graphics device or OS used, nor it seems have you 
taken account of

                 CHANGES IN R VERSION 2.7.0


     o   Considerable efforts have been made to make the default output
         from graphics devices as similar as possible (and in
         particular close to that from postscript/pdf).  Many devices
         were misinterpreting 'pointsize' in some way, for example as
         being in device units (pixels) rather than in points.

Define 'correctly'!  For example, as I recall the X11 device in 2.6.1 was 
not working as documented except on 75dpi and 100dpi screens.

That line does not work correctly for me under either.  I think 
data=InsetSprays is missing.

Well, you set it, so you seem to have set it incorrectly.  It is two lines 
wide on all the devices I tried in 2.7.1.

Nor do we, but RTFM failure seems implicated.
