It is becoming a standard tool for advanced dealing with empirical data, also in
finance.
Some good things about R
- It is freely available for download from the internet, and can be installed
on a wide range of operating systems, such as Windows, Mac OS, Unix, etc.
- There is a large number of packages available for specialized purposes,
also freely dowloadable from the web.
Some issues with R
- It is command-driven, and learning to use it to its full extent takes some time and
effort.
- The documentation is comprehensive, but not always easy to navigate. It is sometimes
necessary to do a bit of googling before one finds examples of how somebody else has
peformed a particular task.
- The large number of packages, sometimes competing against each others, makes it
hard to find the best way of doing things.
