(Um. So what device were you using?)
That example is given by sm.script(air_cont). The solid contour is not
quite closed on all platforms I tried, but the other two are. That includes
rw1001 on NT. The solid contour is also not closed on the S-PLUS original.
Either you have not followed the script exactly or there is problem
specific to your graphics card / printer / ....
Please do read the section on reporting bugs in the FAQ. Without exact
instructions for what you did there is no way we could reproduce this.
Potential bugs in add-on packages are best reported to the authors/porters,
not all of whom read R-help.
