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.

Learn R from Scratch

evenOdd <- function(testVariable)
{
  if(testVariable %% 2 == 0)
  {
    cat("even")
  } else
  {
    cat("odd")
  }
}

# Driver Code
evenOdd(78)
cat("\n")
evenOdd(67)
cat("\n")
evenOdd(1)

evenOdd <- function(testVariable){}

exercise12 <- function(testVariable)
{

evenOdd <- function(testVariable)
{
  if(testVariable %% 2 == 0)
  {
    cat("even")
  } else
  {
    cat("odd")
  }
}

## Explanation
Create a function using the following syntax:
```
evenOdd <- function(testVariable)
{
   <Conditional Block>
}
```
The function takes an argument `testVariable` and accordingly performs some tasks on it.

In this review, we provide a detailed analysis of the given problem.
