_A_r_e _A_l_l _V_a_l_u_e_s _T_r_u_e_?

_D_e_s_c_r_i_p_t_i_o_n_:

     Given a set of logical vectors, are all of the values
     true?

_U_s_a_g_e_:

     all(..., na.rm = FALSE)

_A_r_g_u_m_e_n_t_s_:

     ...: one or more logical vectors.

   na.rm: logical. If true `NA' values are removed before
          the result is computed.

_V_a_l_u_e_:

     Given a sequence of logical arguments, a logical value
     indicating whether or not all of the elements of `x'
     are `TRUE'.

     The value returned is `TRUE' if all the values in `x'
     are `TRUE', and `FALSE' if any the values in `x' are
     `FALSE'.

     If `x' consists of a mix of `TRUE' and `NA' values,
     then value is `NA'.

_E_x_a_m_p_l_e_s_:

     range(x <- sort(round(rnorm(10) - 1.2,1)))
     if(all(x < 0)) cat("all x values are negative\n")
