Print?
After executing the code, you might notice [1] parts in the output. R is just letting you know that this line begins with the first value in your result. In future sections, you will meet outputs that contain multiple values.
As you remember, there is no need to use a special function to output values in R.
Assume we want to perform a division.
python
Suppose you want to 'round' the number up to a specific number of digits. In that case, you can use the traditional programming languages function print().
Let's consider the function' structure:
python
For example, we can round the number from the example above to 3 digits.
python
As you can see, the result of the expression was rounded to three digits.
