The first group of topics lists functions and special help topics that are built into RLaB . The special topics have names in upper case and are of a general nature. Lawyers recommend that you now read the help on topics CONDITIONS and WARRANTY by entering

The subsequent topics refer to commands that have been written in RLaB  script files, which we refer to as ``R-files''. These R-files are stored in directories, which the help command searches. The help files in the .../rlib directory come as a standard part of RLaB , and the remainder refer to local R-files that have been setup for you by whoever installed your RLaB .

In general, the functions listed in the first group are the most efficient as they are compiled into the core of RLaB . In contrast, RLaB 's R-files have the extra overhead of reading and interpretation before they are executed. This lower efficiency associated with R-file interpretation is traded for the benefit of being able to write your own features into RLaB . If an R-file feature is really useful, it can be added to the core RLaB  program since you have the source code2.
