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

     Generates a matrix out of a dataset, each row corresponding to an
     siRNA/gene ID, each column to a channel value or its index in the
     dataset.

_U_s_a_g_e:

     generateRepMatNoFilter(data, minNbReps, IndexOrInt, col4val, col4anno)

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

    data: an R data frame generated with 'generateDatasetFile' 

minNbReps: set to 2 if you want to exclude replicates occurring only
          once in the dataset, otherwise 1. 

IndexOrInt: a character string - either ' "Index"' or ' "Intensities"'
          - specifying which values are to be contained in the output
          matrix. 

 col4val: a character string specifying the name of the dataset column
          to be used for the values of the output matrix (if '
          IndexOrIntensities' is set to ' "Intensities"'), for example
          ' "SigIntensity"' or ' "NbCells"' 

col4anno: a character string specifying the name of the dataset column
          to be used for the output matrix' rows, for example '
          "GeneName"' or ' "Internal_GeneID"'. 

_D_e_t_a_i_l_s:

     The function will not omit values or indexes of lines/wells with
     spot type -1. If you want to omit those, use '
     generateReplicatematrix'.

_V_a_l_u_e:

     A matrix with each row corresponding to an siRNA/gene ID (as
     reflected in rownames), each column to a channel value or its
     index in the dataset. Missing values (in case of different number
     of replicates occuring for different siRNAs/genes) are set to NA.

_S_e_e _A_l_s_o:

     'generateReplicateMat'

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

     data(exampleDataset, package="RNAither")

     replicatematrix <- generateRepMatNoFilter(dataset, 2, "Index", "SigIntensity", "GeneName")
