print() Function
Sveip for å vise menyen
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
125 / 3 print(5 / 3, digits = 3)
Here, the output of print() is rounded to three significant figures, making results easier to read.
