R Introduction: Part I

Using the print() Function

After running the code in the previous chapter, you may have noticed [1] preceding the results. This is R's way of indicating that the line starts with the first element in your output. As you progress through the course, you'll encounter outputs with multiple elements.

Let's say we want to carry out a division operation:


              1
            
5/3

As we already know, in R, it's unnecessary to use a specific function to display output values. However, if your goal is to round a number to a desired number of significant figures, you can use the print() function, which you may also recognize from other programming languages.

Here's how you use the function:

For instance, we can round the division result from our previous example to three significant figures:


              1
            
print(5/3, digits = 3)

As demonstrated, the output of the expression has been rounded to three significant figures.

Tarea

On the first line, execute a division of 50 by 7.
On the second line, divide 50 by 7 again, but this time round the result to four significant figures using the print() function.
