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".

Instructions

Use the example creating a vector of three 3's to create a vector of four 4's using the rep() command.
Use the example creating the vector containing the numbers 2, 4, and 6 in order, to create the vector containing 1, 3, and 5 in order using the seq() command.
The prompts to the first two questions have been created using the c() command. Provide the answers to the first two the same way, using the c() command.
