_D_e_s_c_r_i_p_t_i_o_n:

     View a specified vignette, or list the available ones.

_U_s_a_g_e:

     vignette(topic, package = NULL, lib.loc = NULL)

_A_r_g_u_m_e_n_t_s:

   topic: a character string giving the (base) name of the vignette to
          view.

 package: a character vector with the names of packages to search
          through, or 'NULL' in which case _all_ available packages in
          the library trees specified by 'lib.loc' are searched.

 lib.loc: a character vector of directory names of R libraries, or
          'NULL'.  The default value of 'NULL' corresponds to all
          libraries currently known.

_D_e_t_a_i_l_s:

     Currently, only PDF versions of vignettes can be viewed. The
     program specified by the 'pdfviewer' option is used for this. If
     several vignettes have PDF versions with base name identical to
     'topic', the first one found is used for viewing.

     If no topics are given, the available vignettes are listed.  The
     corresponding information is returned in an object of class
     '"packageIQR"'.  The structure of this class is experimental.

_E_x_a_m_p_l_e_s:

     ## List vignettes in all attached packages
     vignette()
     ## List vignettes in all available packages
     vignette(package = .packages(all.available = TRUE))
