The sample assignment is:
Write a function named continents.gdp with the signature function(my.gapminder, y) which returns a data frame that contains the total GDP on every continent in the year y using the data in the data frame my.gapminder, which is formatted similarly to
gapminder.
The data frame you return should contain the columns continent and gdp (in this order). The rows should be sorted in alphabetical order by continent. Please place the function in the file
ps1.R.
To run the autograder on the provided ps1.R, change the working directory to the location of ps1.R and run Rscript autograde_ps1.R.
The results will bw written to a Gradescope-readable JSON file.
You must change Line 20 of autograde_ps1.R in order to be able to write the autograder output on the server in the correct location.
Note that Gradescope will need to build a new Docker image every time you upload a new autograder, making debugging very annoying. I recommend adding something like wget https://[your server/autograde_ps1.R to run_autograder. This enables you to change the autograder without rebuilding a Docker image every time.
