Statistical Analysis with R

The digital world we live in has given companies and people access to staggering amounts of data, and anyone who can make use of that to drive valuable insights stands to benefit. The ability to work with large amounts of data is becoming a standard requirement for countless jobs across multiple industries.

R, probably the most well-known language for data analysis, has been used for years due to its robust statistical functionality, outstanding graphing ability, and extensibility through packages.

This interactive module will get us up to speed with R and assumes no prior knowledge of it. We'll start with the very basics and work our way up to advanced concepts like exception handling. By the time we're done, we'll be able to write detailed, useful code in R.

# What are Relational Operators?
Relational Operators are used for comparing objects. They return a boolean variable, i.e., `TRUE` or `FALSE`.




number1 <- 10
number2 <- 3

# Equal to
number1 == number2

# Not equal to
number1 != number2

# Less than
number1 < number2

# Less than equal to
number1 <= number2

# Greater than
number1 > number2

# Greater than equal to
number1 >= number2

If you use a relational operator to compare vectors, R will do element-wise comparisons.

> The output of performing relational operations on two vectors is a vector!

In this lesson, we will learn the basic relational operations in R and how to use them.
