### Loading the Iris Dataset and defining a function
The aim of this function is to remove any missing data that may be present in the dataset. 

```{r}

# Defining a function with a single argument called data, that takes the dataset 
# and performs some input transformation on it. 

# Loading the built-in iris dataset in R.
data(iris)

# Creating a function that removes any rows that have missing values values in them. 
remove_nas <- function(data) {
  clean_data <- na.omit(data)
    return(clean_data)
}

remove_nas(iris)

```

### Second function initially created in the dev branch
```{r}

# Creating a function that creates a new column called Sepal.Area, which 
# multiplies their length and width. 
sepal_area <- function(data_new) {
  data_new$Sepal.Area <- data_new$Sepal.Width * data_new$Sepal.Length
    return(data_new)
}

# Applying this function to the iris dataset. 
transformed_data <- sepal_area(iris)

head(transformed_data)

```
