 Publisher's Summary
 Focusing on userdeveloped programming, An R Companion to Linear Statistical Models serves two audiences: those who are familiar with the theory and applications of linear statistical models and wish to learn or enhance their skills in R; and those who are enrolled in an Rbased course on regression and analysis of variance. For those who have never used R, the book begins with a selfcontained introduction to R that lays the foundation for later chapters. This book includes extensive and carefully explained examples of how to write programs using the R programming language. These examples cover methods used for linear regression and designed experiments with up to two fixedeffects factors, including blocking variables and covariates. It also demonstrates applications of several prepackaged functions for complex computational procedures.
