languages/databases, and other languages can easily invoke R's API and result objects. R is commonly used in the fields of finance and statistics. Most people use r because of its statistical function, and R's interior implements a lot of classical or fashionable statistical techniques. Effect DemoWith a simple example, make R look more intuitive.Enter the following command in the console of R:> install.packages (' quantmod ') # Install QUANTMOD Package> Require (QUANTMOD) #引用quantmod包

Defines a point class that represents a point in a three-dimensional space (with three coordinates) and requires the following:1, you can generate a point object with a specific coordinate (construction method);2, provide a method that can set three coordinates (member method);3. Provide a method (member method) to calculate the distance from the pity Dorado to another point;The code is as follows:Note: The file name is Testpoint.java (main Class) Public classpoint{Doublex, Y, Z //Construction M

Each table corresponds to so many classes, and the classes in the Data class library use a lot of stored procedures, which can be cumbersome if we need to write them manually. So we have adopted the method of Codesmith template.It is important to note that in our development process, the template only generates some of the underlying operations related to the code, or there will be a part of the need for us to manually add, even so, the template also helps us do a lot of work.The template genera
