Sure, here's a step-by-step guide on how to answer the assignment:

  1. Submission of R markdown file: You need to submit your answers in a single R markdown file with the file suffix .Rmd. Make sure to include the assignment cover sheet text in your submission. Also, add appropriate text and/or comments to make your thoughts clear to any collaborators.

  2. Obtaining Your Data: The data for the assignment is available in the file provided. Extract the complete set of files and use the file labelled with your student id. The file should be named as a1xxxxxx.csv. Make sure this file is in the same directory as the markdown file.

  3. Tasks in R:

    • Load your allocated file, remove all comments, blank rows and change any encoded missing values to NA.

    • Extract the CellType and Treatment information from the sample names, placing them in separate columns after converting from wide to long form.

    • Create a correctly labelled boxplot of your dCt values for each of the four conditions.

    • Conduct a simple linear regression on your data using the model dCt~CellType + Treatment + CellType:Treatment and include the model output from the function summary() without interpretation.

  4. Research questions:

    • Explain the difference between .csv and .tsv file types and suggest a function for loading a .tsv file into R.

    • Describe the importance of each type of message (error messages, warnings, and general messages) commonly seen in the R Console and what information they are conveying.

    • Explain the difference between an integer and a floating point value. Also, explain why floats are sometimes called “doubles”.

If you are using Google Docs, please export it as a Word document. Academic integrityIt is imperative at UTS that students complete their work with integrity - completing your own work and referencing the contributions of others. UTS conducts regular checks and investigations into work that may breach our integrity standards - this can include plagiarism, improper paraphrasing, collusion and contract cheating (engaging another person to prepare work for you). Turnitin will be run on all submissions and you are able to view your Turnitin report. No references are required in this assessment task because we are asking you to write about your own thoughts, feelings and perceptions. If you do choose to use any outside sources, please use in-text referencing in accordance with APA 7 - refer to the UTS APA 7 Library guide for more information.By submitting your assessment task, you are certifying thatthis is your own work in your own wordsyou have appropriately recognised the work of others (if used) through appropriate APA 7 referencingthat you have not published or shared your completed work to any notes sharing sites (as this is a breach of UTS' rules related to misconduct because it is helping others cheat)that the work has not been previously submitted for assessment in this subject or any other  (if you are repeating AAA, you should write an entirely new/fresh reflection)Your assessment submission will be processed through Turnitin. Where the teaching staff have concerns about whether you have completed your own work (for example, your document has low editing time, a low version number or does not appear to be written by you for any other reason) - you may be asked to provide documentation showing the drafting process you have undertaken in reaching your final submission. This process is similar to real-world accounting, where documents showing the preparation of the financial statements, accounting advice to clients, tax advice or the audit report/opinion are commonly referred to as 'working papers' and must be produced by regulatory bodies on request. For students, your working papers for this assignment can include notes, drafts, access to cloud-stored documents in services such as Google Drive or OneDrive, or internet search history related to the assessment task. It is recommended that you retain these notes, drafts etc for at least 4 months after the end of the teaching session (businesses and accountants in Australia are required to keep their working papers for 7 years). Failure to be able to produce material on request from your coordinator, Academic Integrity Officer or Responsible Academic Officer of the university may be used in misconduct allegations against you. Any request will be made to you in writing to your UTS email address.
