With all systems ready to launch, let's start our first commands. R will take both the strings in quotes or simple numbers. Here, we will put one command as a string and one command as a number. The output is the same as the input:

```    > "Let's Go Sioux!"     "Let's Go Sioux!"        > 15     15
```

R can also act as a calculator:

```    > ((22+5)/9)*2     6
```

Where R starts to shine is in the creation of vectors. Here, we will put the first 10 numbers of the Fibonacci sequence in a vector using the c() function, which stands for combining the values to a vector or list (concatenate):

```    > c(0, 1, 1, 2, 3, 5, 8, 13, 21, 34) #Fibonacci sequence       0  1  1  2  3  5  8 13 21 34
```

Note that in this syntax, I included a comment, Fibonacci sequence. In R, anything ...
