R For LoopA for loop is the most popular control flow statement. A for loop is used to iterate a vector. It is similar to the while loop. There is only one difference between for and while, i.e., in while loop, the condition is checked before the execution of the body, but in for loop condition is checked after the execution of the body. There is the following syntax of For loop in C/C++: How For loop works in C/C++?The for loop in C and C++ is executed in the following way:
For loop in R ProgrammingIn R, a for loop is a way to repeat a sequence of instructions under certain conditions. It allows us to automate parts of our code which need repetition. In simple words, a for loop is a repetition control structure. It allows us to efficiently write the loop that needs to execute a certain number of time. In R, a for loop is defined as :
Flowchart Example 1: We iterate all the elements of a vector and print the current value. Output Example 2: creates a non-linear function with the help of the polynomial of x between 1 and 5 and store it in a list. Output Example 3: For loop over a matrix Output Example 4: For loop over a list Output Example 5: count the number of even numbers in a vector.# Create a list with three vectors. Output
