About the Talk:
Although data cleaning is a frequent topic of conversation (and commiseration) in the world of data science, data validation---somewhat surprisingly---is discussed relatively less often. So in this talk, data validation will take centre stage, as we take a look at what it is (and is not), as well as some guiding principles, best practices and overall criteria to assess/ensure data validity. The talk will also cover several R packages aimed at this precise topic, for instance: {validate}, {assertr} and {ensurer}, as well as other related packages or functions, with examples provided as we go along. By the end of this talk, the aim is to have provided an overview on the principles and tools in this area, while highlighting the importance of the topic itself.
