For example. Assume I do: dev.new(width=5, height=4) plot(1:20) And now I wish to do plot(1:40) But I want a bigger window for it.

The only solution I see to it would be t...

Hi All, I want to have an abstract base class for some of my custom UserControl's. The reason is obvious: they share some common properties and methods (a basic implementation of some elements of an interface actually), and I want to implement them only once.

But what I need to know now is if/how I can cast various functions (in the base class) to return the subclass object. This is both for a given function but also a function call in it. (I'm work...
class Base { public: Base() {} void Foo(int x) {...} }; class Derived : public Base { public: Derived(int args) { /* process args in some way */ Foo(result); } }; Is it allowed to call a method of the base class in the constructor of the derived class? I would imagine this is fine as the Base ...

The BASE acronym is used to describe the properties of certain databases, usually NoSQL databases. It's often referred to as the opposite of ACID. There are only few articles that touch upon the details of BASE, whereas ACID has plenty of articles that elaborate on each of the atomicity, consistency, isolation and durability properties....
I haven't found a clear answer to this question (but have determined the HTML tag is more trouble than it's worth.)
