Question: For this R exercise, you must make sure that an internet connection is already secured as some of the commands that you will be using in this exercise requires a stable internet connection. Also, your first attempt on this exercise must be done individually (rather than in group). After your first attempt, however, you will engage in a peer review by which you assess your groupmate's codes and, when needed, improve upon it.
You are first asked to search for the following variables in WDI dataset (for your reference, the exact indicator names are provided in parenthesis):
real effective exchange rate (PX.REX.REER)
external balance (NE.RSB.GNFS.KN)
After all peer reviews are done, choose the best (or the ultimate) set of codes. Copy and paste it here. In doing so, include every single line, so I can also run it on my end if needed.
You are then asked to compute the coefficient of correlation between the above variables for the US from 2001 to 2019.
What is the coefficient of correlation between real effective exchange rate and external balance for the US from 2001 to 2019?
List at least one new thing that your group learned as part of the peer review process.
