Dear R-users,

I am trying to figure out why I cannot print vignettes in my new R
installation (R.11 on opensuse 11.2). Apparently, vignette objects are
properly created but could not be printed:

> z<-vignette('grid')
> str(z)
List of 3
 $ file : chr "/usr/lib/R/library/grid/doc/grid.Snw"
 $ pdf  : chr "/usr/lib/R/library/grid/doc/grid.pdf"
 $ topic: chr "grid"
 - attr(*, "class")= chr "vignette"
> z
sh: : command not found

What would you suggest me to do to perform a step-by-step debugging of the
vignette-specific print function?

Thank you

Sebastien
