Auxiliary Function to Set/View Defaults for Arguments of pdf

Description:

     The auxiliary function 'pdf.options' can be used to set or view
     (if called without arguments) the default values for some of the
     arguments to 'pdf'.

     'pdf.options' needs to be called before calling 'pdf', and the
     default values it sets can be overridden by supplying arguments to
     'pdf'.

Usage:

     pdf.options(..., reset = FALSE)

Arguments:

     ...: arguments 'width', 'height', 'onefile', 'family', 'title',
          'fonts', 'paper', 'encoding', 'pointsize', 'bg', 'fg',
          'pagecentre', 'useDingbats' and 'colormodel' can be supplied.

   reset: logical: should the defaults be reset to their
          'factory-fresh' values?

Details:

     If both 'reset = TRUE' and '...' are supplied the defaults are
     first reset to the 'factory-fresh' values and then the new values
     are applied.

Value:

     A named list of all the defaults.  If any arguments are supplied
     the return values are the old values and the result has the
     visibility flag turned off.

See Also:

     'pdf', 'ps.options'.

Examples:

     pdf.options(bg = "pink")
     utils::str(pdf.options())
     pdf.options(reset = TRUE) # back to factory-fresh
