The dataset name has been changed to 'Melanoma_df' to avoid confusion with other datasets from packages in the R ecosystem and to follow the naming conventions of the 'MedDataSets' package. The suffix '_df' indicates that this dataset is a data frame, helping to distinguish it from other datasets within the package and from those in the broader R ecosystem. The original content of the dataset has not been modified in any way.
