_U_s_a_g_e:

     type2Exten(type, datatype)

_A_r_g_u_m_e_n_t_s:

    type: method type.

datatype: data type.

_D_e_t_a_i_l_s:

     For every 'datatype' different methods, i.e. algorithms exist
     which can be applied. Valid 'datatype's are 'preprocess' and
     'normation'.

     For 'datatype' 'preprocess' the following methods can be applied:

       'mean':           trimmed mean
       'median':         median
       'quantile':       quantile
       'tukeybiweight':  tukey biweight
       'medianpolish':   median polish

     For 'datatype' 'normation' the following methods can be applied:

       'mean':      trimmed mean
       'median':    median
       'quantile':  quantile
       'lowess':    lowess
       'supsmu':    supsmu

     The tree extensions are described in 'validTreetype'.

_V_a_l_u_e:

     A 'character' with the correct tree extension.
