aggregate Implicational aggregation of rules' consequents into a fuzzy set
antecedents Extract antecedent-part (LHS) of the rules in a list
as.matrix.fsets Convert a 'fsets' object into matrix
cbind.fsets Combine several 'fsets' objects into a single one
consequents Extract consequent-part (RHS) of the rules in a list
defuzz Convert fuzzy set into a crisp numeric value
evalfrbe Evaluate the performance of the FRBE forecast
farules A class of rules with statistical characteristics.
fcut Transform data into a set of fuzzy attributes using triangular or raised cosine shapes of the fuzzy sets
