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

     Calculates a _Fuzzy Pattern_ for each category. To do this, a
     given percentage of the samples belonging to a category must have
     the same label (Low, Medium or High).

     calculateFuzzyPatterns(rmadataset, dvs, piVal = 0.9, overlapping = 2)

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

rmadataset: 'ExpressionSet' with numeric values containing gene
          expression values (rows) of samples belonging to different
          categories (columns).
            The 'ExpressionSet' also contains an 'AnnotatedDataFrame'
          with metadata regarding the classes to which each sample
          belongs.

     dvs: Matrix containing discrete values according to the
          overlapping parameter after discretizing the gene expression
          values.
            Includes an attribute types which determines the category
          of each sample.

   piVal: Controls the degree of exigency for selecting a gene as a
          member of a _Fuzzy Pattern_.
           'Default value = 0.9'. 'Range[0,1]'. 

overlapping: Modifies the number of membership functions used in the
          discretization process.
            Possible values: 

             1.  Low, Medium, High.

             2.  Low, Low-Medium, Medium, Medium-High, High.

             3.  Low, Low-Medium, Low-Medium-High, Medium,
                Medium-High, High.

          'Default value = 2'. 

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

     Genes belonging to each _Fuzzy Patterns_. There are one FP for
     each class.
      Includes an attribute ifs with the _Impact Factor_ for each
     category.
