Using R

With all the systems ready to launch, let's start our first commands. R will take both the strings in the 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 ten 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 after the # key on the command line is not executed.

Now, let's create an object that contains these numbers of the sequence. You can assign any vector or list to an object. In most of the R code, you...
