There can be many methods available for importing data into the R program or can be entered manually from an external source, which may include text files, spreadsheets, datasets from statistical packages, and database-management systems. Once a dataset is created, in this workshop we will try to annotate it, adding descriptive labels for variables and variable codes and on functions for modifying the datasets according to our needs.
