在下载了R 语言的安装包后，打开README才知道，线性代数的英语是: linear-algebra。
Our aim at the start of this project was to demonstrate that it was
possible to produce an S-like environment which did not suffer from
the memory-demands and performance problems which S has. Somewhat
later, we started to turn R into a "real" system, but unfortunately we
lost a large part of the efficiency advantage in the process, so have
revised the memory management mechanism and implemented delayed
loading of R objects. A lot of performance tuning has been done,
including the ability to use tuned linear-algebra libraries.
Longer-term goals include to explore new ideas: e.g. virtual objects
and component-based programming, and expanding the scope of existing
ones like formula-based interfaces. Further, we wish to get a handle
on a general approach to graphical user interfaces (preferably with
cross-platform portability), and to develop better 3-D and dynamic
