Main data. Distances among rows are calculated if y=NULL. Must be a data frame. |
y |
Suplementary data matrix. If not NULL the distances among the rows of x and y are calculated. Must be a data frame with the same columns as x. |
Classes |
Vector containing the classes of each variable. |
transformation |
Transformation to apply to the similarities. |
BinCoef |
Coefficient for the binary data |
ContCoef |
Coefficient for the continuous data |
NomCoef |
Coefficient for the nominal data |
OrdCoef |
Coefficient for the ordinal data |
