bookprint() Function

When R displays results, the output is often preceded by [1]. This marker indicates that the line begins with the first element of the result. For larger outputs, you will see additional markers such as [2], [3], and so on.

Using print()

Although R automatically shows results, you can use the print() function to control how output is displayed. One of its options is the digits argument, which rounds numbers to a chosen number of significant figures.

print(expression, digits = n)

Example

12
5 / 3 print(5 / 3, digits = 3)
copy

Here, the output of print() is rounded to three significant figures, making results easier to read.

Oppgave

Swipe to start coding

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