_D_e_s_c_r_i_p_t_i_o_n:

     This widget is called by expresso to allow users to select
     correction methods that will be used to process affy data.

_U_s_a_g_e:

     expressoWidget(BGMethods, normMethods, PMMethods, expMethods, BGDefault,
     normDefault, PMDefault, expDefault) 

_A_r_g_u_m_e_n_t_s:

BGMethods: 'BGMethods' a vector of character strings for the available
          methods that can be used as a background correction method of
          affy data

normMethods: 'normMethods' a vector of character strings for the
          available methods that can be used as a normalization method
          of affy data

PMMethods: 'PMMethods' a vector of character strings for the available
          methods that can be used as a PM correction method of affy
          data

expMethods: 'expMethods'a vector of character strings for the available
          methods that can be used as a summary method of affy data

BGDefault: 'BGDefault' a character string for the name of a default
          background correction method

normDefault: 'normDefault' a character string for the name of a default
          normalization method

PMDefault: 'PMDefault' a character string for the name of a default PM
          correction method

expDefault: 'expDefault' a character string for the name of a default
          summary method

_D_e_t_a_i_l_s:

     The widget will be invoked when expresso is called with argument
     "widget" set to TRUE. Default values can be changed using the drop

     list makes an selection. The first element of the list for
     available methods will be the default method if no default is
     provided.

_V_a_l_u_e:

     The widget returns a list of selected correction methods. 

      BG: background correction method

    NORM: normalization method

      PM: PM correction method

     EXP: summary method

_N_o_t_e:

     The functions are part of the Bioconductor project at Dana-Farber
     Cancer Institute to provide Bioinformatic functionalities through
     R
