Creating Vectors in R

Vectors can be analyzed in a few different ways in R.

One way is to create the vector yourself, and there are a few different means by which you can do this.

The rep() command in R creates a vector that repeats the same element a prescribed number of times, while the seq() command creates a vector that follows a prescribed pattern.

A vector can be manually created by using the c() command, which stands for "concatenate".
