Vectors

Vectors are used to store single or multiple values of similar data types in a variable and are considered to be one-dimensional arrays. That means that the x variable we just defined is a vector. If we want to create a vector with multiple numeric values, we assign as before with one additional rule: we put all the values inside c() and separate all the values with , except the last value. Let's look at an example:

val = c(1, 2, 3, 4, 5, 6)

What happens if we mix different data types such as both numerics and characters? It works! (A variable's name is arbitrarily named as val, but you can name your variable anything that you feel appropriate, anything!) Except in some cases, such as variable names, shouldn't start with any special ...
