Control structures are an essential aspect of any programming language, including R. They allow you to control the flow of your program by making decisions, repeating actions, and defining the order in which statements are executed. In R, there are several control structures that help you achieve...
Control structures in R allow you to control the flow of execution of the program, depending on runtime conditions. Common structures are: if, else: testing a condition for: execute a loop a fixed number of times while: execute a loop while a condition is true repeat: execute an infinite ...

The function of a looping statement is to execute a block of code, several times and to provide various control structures that allow for more complicated execution paths than a usual sequential execution. The types of loops in R are as follows: ...
Chapter 5. Statements and Control Structures Consider the following Ruby program. It adds two numbers passed to it on the command line and prints the sum: x = ARGV[0].to_f # … - Selection from The Ruby Programming Language [Book]
Blocks can be useful to refer to the other control structures in AL.When begin follows, then, else, or do should be on the same line and preceded by one space character.Example 1AL 複製 if (x = y) and (a = b) then begin x := a; y := b; end; ...
Overview of PL/SQL Control Structures According to thestructure theorem, any computer program can be written using the basic control structures shown inFigure 4-1. They can be combined in any way necessary to deal with a given problem.
aAn area in programming language research is the identification of useful controlstructures and the development of syntactic structures to represent them. Along these lines I like to use the example of trying to find a particular value in an array using the equivalent of a "for" statement. The...
Obviously, there’s not much you can do at that point, so it’s time to dive deeper into Python by examining its flow control structures, like if/then statements, loops and exceptions. One thing before I begin, though: I never really touched on the subject of editors. While mos...
