vita.had.co.nzKeywords: data cleaning, data tidying, relational databases, R. 1. Introduction It is often said that 80% of data analysis is spent on the process of cleaning and preparing the data (Dasu and Johnson2003). Data preparation is not just a rst step, but must be repeated many over the course of analysis as new problems come to light or new data is ...
