Popis:	For arrays, matrices, vectors, lists, and expressions, there are a number of functions that describe various attributes of an object. Also, there are a number of functions that manipulate objects to create new objects. The functions covered in this chapter are the descriptive functions dim(), nrow(), NROW(), ncol(), NCOL(), length(), and nchar(); and the functions that manipulate objects: cbind() and rbind(); the apply functions; sweep(), scale(), and aggregate(); the table functions; and functions tabulate(), and ftable().
