The R Script

Now that we have learned how to organize and format data using R functions, we are now ready to perform calculations and data analysis. We do this with what is called R script. In the final video presentation of this eLesson, we will demonstrate how to perform the correlation coefficient calculation using a few rows from Sarah's data set.

Complete this next exercise to practice this technique and make sure you are understanding R scripting correctly.
