The Essential R Reference is essentially a comprehensive combination of dictionary, glossary and thesaurus for the R programming language. The book will be arranged into logical sections so that the reader can find the topic they require help on quickly. Each topic will be split into smaller chunks with a final entry for each command. The command entries will consist of a guide to the common uses for the command and allow the reader to type the appropriate command into the computer. Each entry will also link to related entries allowing ease of lookup for the reader.
