In the video, he explains different ways how to change options and global settings in R. If you want to learn more about the handling of numbers in R, I can recommend the following video of the YouTuber Anthony Damico.
If you are confused by this, be sure to check out my YouTube video on Inferences with Regression. 379SD, before adding all of it together to obtain our predicted value. So, we are going to use Excel to multiply. If we would like to change the options back to the default specification, we would have to restart RStudio, or we would have to save the default specification in the forefront.įurther Resources for Dealing with Numbers in R As you can see, the unstandardized regression equation from these results was: y. Note: The amount of digits has now been changed for our entire R session. If there would be more digits before the decimal point, the number of digits after the decimal point would be reduced (e.g. In our specific example, 2 digits before the decimal point and 3 digits after the decimal point. Think of them as a line chart thats been wrapped around a central point, where the y-axis of the line chart starts from the central point and extends. options(digits = 5)), we changed the number of maximum digits to 5.
You have formatted the column its in to display just 1 decimal place. As you can see, the console output is a number with only three decimal places (in contrast to the five decimal places that we had before). For example, in your Excel spreadsheet you have a cell with the value 5.1234.
