	_D_e_s_c_r_i_p_t_i_o_n:
	
	     This function allows user to set and examine a variety
	     of global ``options'' which affect the way in which R
	     computes and displays its results.  digits controls the
	     number of digits to print when printing numeric values.
	     It is a suggestion only.  expressions sets a limit on
	     the number of nested expressions that will be
	     evaluated.  This is especially important on the Macin-
	     tosh since stack overflow is likely if this is set too
	     high.
	
	     width controls the number of characters on a line. You
	     may want to change this if you resize the window that R
	     is running in.  prompt must be a quoted string. The
	     expression inside the quotes will be used for the
	     prompt.  continuation must be a quoted string. It sets
	     the prompt used for lines which continue over one line.
	     editor sets the default text editor.  Invoking options
	     returns a list with the current values of the options
	     stored in it.
