_D_e_s_c_r_i_p_t_i_o_n:

     `range' returns a vector containing the minimum and maximum of all
     the given arguments.

_U_s_a_g_e:

     range(..., na.rm = FALSE)
     range.default(..., na.rm = FALSE, finite = FALSE)

_A_r_g_u_m_e_n_t_s:

     ...: any `numeric' objects.

   na.rm: logical, indicating if `NA''s should be omitted.

  finite: logical, indicating if all non-finite elements should be
          omitted.

_D_e_t_a_i_l_s:

     This is a generic function; currently, it has only a default
     method (`range.default').

     It is also a member of the `Summary' group of functions, see
     `Methods'.

     If `na.rm' is `FALSE', `NA' and `NaN' values in any of the
     arguments will cause NA values to be returned, otherwise `NA'
     values are ignored.

     If `finite' is `TRUE', the minimum and maximum of all finite
     values is computed, i.e., `finite=TRUE' includes `na.rm=TRUE'.

_S_e_e _A_l_s_o:

     `min', `max', `Methods'.

_E_x_a_m_p_l_e_s:

     print(r.x <- range(rnorm(100)))
     diff(r.x) # the SAMPLE range

     x <- c(NA, 1:3, -1:1/0); x
     range(x)
     range(x, na.rm = TRUE)
     range(x, finite = TRUE)
