Instructions
To complete this assignment, add code as needed into the R code chunks given below, and, where applicable,
replace the “Delete me” and add in your own text response. Be sure when adding in text responses to never
copy-paste symbols from outside of the document. Only use the symbols on your keyboard. Do not delete
the question text, or modify any other part of the code except for the “author” in Line 3.
All calculation output must be visible in the final document, and all text responses should be in complete
English sentences. When you are done You may speak to your class mates about ideas and what func-
tions/optional arguments you may need to use but you may not directly show your code/output to your
classmates. To be clear, you may talk as much as you like but you can not look directly at someone else’s
completed work, and you cannot share your code with any of your classmates. If you have an issue that you
can’t resolve without someone looking at your work (e.g. you get an error when knitting your document),
please see the Help Centre in 311 Machray Hall. To compile this document as a PDF to submit or to view
your intermediate work/output (I suggest you compile it after every question), click on the knit button above
this window.
To properly see the questions, complete the setup and then knit this .Rmd file to .PDF and view the output.
You will have a link in your email that takes you to the Crowdmark submission page. Once you have
completed the worksheet, knit it to .PDF and upload your output to Crowdmark. Also, upload your .Rmd
file to Crowdmark where prompted. To see where your .Rmd file is saved, click File > Save As in the top-left
of your screen. Make sure you set your Name and Student Number in the Author section of this document
(Line 3). Do not alter the title or the date. Please note that if you do not submit a knit .PDF file, you will
given a grade of zero.
After you knit your assignment to PDF, check your code chunks. If your code at any point runs off the page,
find the nearest comma, click to the right of it, and press Enter (or Return if you are on a Mac). This will
force a break in the code so that it goes onto the next line. All of your code must be readable in the final
submission.
Your full submission is due by 11:59 p.m. on October 21st. Crowdmark may allow you to submit late, but
you will be given an automatic grade of zero. Be sure to change the author of this file to your own name and
student ID number. All numerical and graphical answers must be done using R, unless stated otherwise.
