Preface. This introduction to R is derived from an original set of notes describing the S and S-PLUS environments written in 19902 by Bill Venables and David M. Smith when at the University of Adelaide.Combining Matrices. The columns of two matrices having the same number of rows can be combined into a larger matrix. For example suppose we have another matrix C Data structures. This chapter summarises the most important data structures in base R. Youve probably used many (if not all) of them before but you may not have thought deeply about how they are interrelated.

Functions. R functions are invoked by its name then followed by the parenthesis and zero or more arguments. The following apply the function c to combine three numeric values into a vector.The conversion from a matrix to a data frame in R cant be used to construct a data frame with different types of values. If you combine both numeric and character data in a matrix for example everything will be converted to character.In two dimensions the standard rotation matrix has the following form [ ].This rotates column vectors by means of the following matrix multiplication [ ] [ ] [].
