A vector is a collection of elements, a basic data structure. Vectors are crucial in RStudio because they can used to represent variables. The data types contained by a vector could be logical e.g (TRUE, FALSE), integer e.g (1, 2, 3), or character e.g ("Roula", "Micheal").

The c() function is very useful as it allows us to create a vector in R. The c stands for combine (or concatenate), because multiple elements are combined into a vector.

x <-c(1,2,3,4,5,6,7,8,9,10)

An important property of vectors is their length. The length of a vector is the count of how many elements are within it.


Additionally, you may create a vector using the seq() function. The seq() function generates a sequence of numbers. For example, if you want to generate a sequence of numbers from 0 to 30 incremented by 3 you can do so using the following command

seq(from=0, to=30, by=3)
