-
- _A_r_g_u_m_e_n_t_s:
-
- x : a numeric vector containing the values whose
- mean is to be computed.
-
- trim : the fraction (0 to 0.5) of observations to be
- trimmed from each end of x before the mean is
- computed.
-
- na.rm : a logical value indicating whether NA values
- should be stripped before the computation
- proceeds.
-
- _D_e_s_c_r_i_p_t_i_o_n:
-
- If trim is zero (the default), the arithmetic mean of
- the values in x is computed. If trim is non-zero, a
- symmetrically trimmed mean is computed with a fraction
- of trim observations deleted from each end before the
- mean is computed.
-
- Missing values are ignored.
