We can create a vector in R by combining different values into a vector. By doing so, we have created a variable known as victor in the global environment pane. This can be called to the screen by typing in the name of the variable, victor, and we can see the vector on the screen. A vector is the simplest type of data structure in R. It is a sequence of data elements, all of the same basic type. These elements can be referred to as components. So each of my different one, two, three, four are components of my vector known as victor. These elements are ordered, and each has a unique index. 

In this case, the one here refers to the index of the first element. I can create vectors for different measurements, such as movie ratings. Maybe I went to see the same film three times, or I add three different people giving me three different ratings for the same film. I could also use a vector to measure different films for each of my three friends. And so I would maybe have my ratings stored in one vector, as such. Jane's ratings stored in a separate vector. Lenny's ratings stored in a separate vector. 

I can find out the number of individual values stored by using the length command. I can append and edit my ratings. If I ended up seeing another film that I wanted to attach to the original four films I've seen. I can combine various different people's ratings, many different vectors together. There are some basic types that we should have, which include the numerics, the logicals, characters, integers, and complex. These are known as the basic types. To repeat the statement at the beginning, a vector is sequence of data elements of the same basic type.
