Likewise with data analysis, a small mistake in your model can lead to a big mistake in your results. Combining the two disciplines means that it is all too easy for a missed minus sign to generate a false prediction that you don't spot until it's too late. Testing is the only way to be sure that your code, and your results, are correct.\u003c\/p\u003e\u003cp\u003eTesting R Code teaches you how to perform development-time testing using the testthat package, allowing you to ensure that your code works as intended. The book also teaches run-time testing using the assertive package; enabling your users to correctly run your code.\u003c\/p\u003e\u003cp\u003eAfter beginning with an introduction to testing in R, the book explores more advanced cases such as integrating tests into R packages; testing code that accesses databases; testing C++ code with Rcpp; and testing graphics. Each topic is explained with real-world examples, and has accompanying exercises for readers to practise their skills -- only a small amount of experience with R is needed to get started!\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Richard Cotton\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1498763650\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781498763653\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e CRC Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 01\/19\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 196\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.95lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.30h x 6.20w x 0.60d","brand":"Richard Cotton","offers":[{"title":"Hardcover","offer_id":48113594925311,"sku":"9781498763653","price":68.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_e05f5ca9-5205-478d-969f-acaa8ad2c2ce.jpg?v=1769616039","url":"https:\/\/www.whiterainbookhouse.com\/products\/testing-r-code-richard-cotton-9781498763653","provider":"WR Book House","version":"1.0","type":"link"}
