The digital transformation of business, the emerging customer-centric business models as well as advanced tools and techniques for analysis imply the need for a marketing culture focused on data and analysis. This monograph explores and presents approaches, algorithms, techniques and procedures for analyzing the market basket with data from sales transactions. Although the statement is based on solid theoretical sources, the main emphasis is placed on the methodology and extraction of patterns from large datasets by using association rules. Guided by the understanding of the leading role of transactional data from sales transactions in mining personalized information and patterns of customer behaviour, our goal is to provide the reader with specific practical guidelines and reproducible operating procedures for market basket analysis with the R programming language. The overall approach of the study is based on specific examples, work instructions, program code and guidelines for interpreting the results in the context of supporting marketing decisions in commercial enterprises.
