Descriptive Functions and Manipulating Objects
Margot Tollefson · Apress eBooks · 2014
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() . These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
