R is a statistical computing and graphics language widely used in data science, statistics, and research. Created in the early 1990s by Ross Ihaka and Robert Gentleman at the University of Auckland, R provides an extensive ecosystem of packages (over 20,000 on CRAN) that extend its core functionality for specialized domains. What makes R particularly powerful is its vectorized nature — operations apply to entire data structures without explicit loops, making code both concise and efficient. When working with R, remember that everything is an object, and understanding R's data structures and functional programming paradigm will dramatically improve your ability to write idiomatic, high-performance code.
