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!"[1] "Let's Go Sioux!"> 15[1] 15

R can also act as a calculator:

> ((22+5)/9)*2[1] 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[1] 0 1 1 2 3 5 8 13 21 34

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