R Programming Fundamentals

Vectors

A vector is an object that holds a collection of various data elements in R, though they are limited because everything inside of a vector must all belong to the same variable type. You can create a vector using the method c(), for example:

 vector_example <- c(1, 2, 3, 4)

In the above snippet, the method c() creates a vector named vector_example. It will have a length of four and be of class numeric. You use c() to create any type of vector by inputting a comma-separated list of the items you'd like inside the vector. If you input different classes of objects inside the vector (such as numeric and character strings), it will default to one of them.

In the following code, we can see an example where the class of the vector is a
