In this article will learn how to create empty vectors in R and then add elements to it in many ways. 1. using c () function. 2. assigning NULL. 3. using rep () function. 4. using vector () function. 5. using numeric () function. In C++ one can create an array of predefined size, such as 20, with int myarray [20]. However, the online documentation on vectors doesn't show an alike way of initialising vectors: Instead, a vector should be initialised with, for example, std::vector myvector (4, 100);. This gives a vector of size 4 with all elements being the value 100.
