_D_e_s_c_r_i_p_t_i_o_n:

     Takes a Codelink object and calculate fold changes (M) between two
     conditions  (samples). Then select genes based on those who pass
     the passed cutoff.

_U_s_a_g_e:

       fc2Cond(object, cond1=NULL, cond2=NULL, fc=1.0, verbose=FALSE)

_A_r_g_u_m_e_n_t_s:

  object: an object of class "Codelink".

   cond1: numeric or character; First condition to compute M.

   cond2: numeric or character; Second condition to compute M.

      fc: value of the fold change cutoff

 verbose: logical; if some information is printed on the console.

_D_e_t_a_i_l_s:

     Conditions can be passed as characters or as numeric index from
     the sample  slot. The intensities are internally transformed to
     log2 if needed. The M value  is computed as:

     M = cond1 - cond2

_V_a_l_u_e:

     A logical vector indicating which genes pass the cutoff
