V learns numbers

Once upon a time there was a vector named V that was feeling empty and was trying to learn numbers from 0 through 9. One day V met the magical combine function c() that was able to add the numbers inside V, like this:

V <- c(1,2,3,4,5,6,7,8,9)

V was very happy, and V was now spending its time enumerating the numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9. Sometimes it would pick one at random:
8 and it was pleased that it was not always the same number coming up.

V wonders about itself

Wanting to know itself better V asked:

  • what is my class? And the answer was: numeric
  • how long am I? And the answer came as 9

V wants more

But then V wanted more: it wanted to add these numbersbut not in the open like this, it wanted to do that “in its head” so it could be done like this: 45 (and the value will be printed here directly as calculate by R.)

V meets the Math Wizard

But how to describe that to Math Wizards?
V asked the beloved fairy friend Equation who gave V the magic codes:

\[\sum_{n=1}^{9} n = sum(V)\]

which is still 45.

V in the land of vectorization

But V wanted more again… V wanted to be 10 times more. So V went on a journey across the land to know what to do. It was a long and arduous journey, but V ended in the Land of Vectorization and there, V was augmented 100 times to be like this: 100, 200, 300, 400, 500, 600, 700, 800, 900. But it was cumbersome to feel these big numbers and division helped one more time to make it just 10 times smaller to be 10, 20, 30, 40, 50, 60, 70, 80, 90

V and the mental picture

This time V wanted to have a mental “picture” of the numbers and V could think of 2 ways, the R code had to be kept secret so that the code would not be stolen:

Conclusion

It is useful to have friends that help you, and V is very grateful for the magical encounter with c() and other friends along the way.
