Be mindful of what is considered quantitative and qualitative data. R indicates what a factor or an integer variable. A factor variable is often on qualitative data, while the integer variable is qualitative data. str(data) - indicates the inconsistencies of the data, ie the data that should not be include or is invalid respective to the context.
