Writing your thesis

Bernhard Bieri

2022-11-09

{iheiddown}’s primary feature is to enable students of the Institute to write their thesis in R-Markdown. It takes care of the annoying formatting process and automates the most repetitive tasks a student faces when writing scholarly documents. In short, {iheiddown} allows its users to focus on the content rather than the formatting of a thesis.

This guide will show you how to get up and running and start writing your thesis in R while providing you with helpful tips and tricks to make you familiar with the workflow of writing your very own scholarly documents in R.

Installation

The installation process is the same than for the thesis template. You’ll need the following software:

  1. Install R and R-Studio
  2. Install a LATEX distribution:
  3. Install {iheiddown} by typing the following command install.packages("iheiddown") in the R-Studio console.

Note: typing remotes::install_github("jhollway/iheiddown") will provide you with the latest version from GitHub.

Create your first thesis project

Creating your first thesis is easy! Let’s look at how it is done. Before we begin, we have to create a new R project by clicking on the file tab in the top of the RStudio window and following the instructions of the prompt that appears. Now that we have created an R project for our presentation, we can open a new R-Markdown file. To do this click on the “plus file” logo in the top left corner and then on “R-Markdown”.

Step 1: Open a project

Step 1: Open a project

After you have done this, a little pop-up helper will appear. The first thing we will do is to select the {iheiddown} template for our thesis. To do so, click on the “From Template” option on the left and select the “Thesis {iheiddown}” template. Now give your thesis a name and click on “OK”.

Important note! Name your project index. This makes sure that the main Rmd file is called index.Rmd which is required to render your thesis with our {bookdown} based rendering function. Don’t worry though, you can rename the folder to your project name after creating it.

Step 2: Select a template

Congrats! You just created your first thesis project!

Hold on, this doesn’t look anything like a Word processor!? To see your thesis, you have to “knit” the code by clicking on the little “knit” button while viewing the 00-MyThesis.Rmd file. This will run all the code chunks in every chapter and convert the Markdown code to a correctly formatted PDF document that you will find in the \versions folder of your project.

Take a moment to read through the generated PDF to get acquainted with the {R-Markdown} syntax and to get a feel of the possibilities of {iheiddown}’s thesis template. This first document is as much a tutorial as this vignette!

Edit your thesis

This section will focus on giving you an overview of the elements of an {iheiddown} thesis and give you a few tips and tricks to edit it.

The different elements of a {iheiddown} thesis

After this initial preview, let’s look at how the thesis project is structured to better understand how to edit it.

The index file

The index file contains two things: the YAML header and the preface of your thesis. It is also the backbone of your thesis in the sense that this is where you will want to knit your whole thesis from.

The YAML header is the place where the main options, metadata and formatting parameters are set. You can set the title of your presentation here, add your name, change the front matter of your thesis (abstract, acknowledgments, table of content, etc.).

The second element in this file is the preface. The only crucial thing to know here is that in order to create your package bibliography (the software you use to render your thesis) you need to leave the first code chunk there.

The chapters

The chapters contain the meat of your thesis, this is where you will outline your idea, run your analyses and draw your conclusions.

Chapters are structured in a similar way, so let us open the 01-introduction.Rmd chapter. In it, you will first find a YAML header that where you can set various chapter level metadata and options.

Note that if for some reason you rename the chapter, you will need to specify the new name in the YAML header too under the input option. Once you have done this you can write away!

The last thing to know about individual chapters is that you can knit them individually. This comes in handy when you want to generate only one part of your thesis for preview purposes.

The appendix and the references files

These files are a bit special as you might notice when you open them.

The 99-references.Rmd file generates the bibliography. This happens automatically, so you will most likely not need to alter this file. Just know that you can set the title of the reference section in the first line.

The 98-appendix.Rmd file allows you to showcase code, additional outputs and more in a separate section to avoid unnecessarily cluttering the main body of your thesis. This can be done by referencing code chunks from your main body and printing the computations you did in your R chunks or by adding new ones.

The _bookdown.yml file

The _bookdown.yml file contains additional information for the YAML header of the main .Rmd file. A standard user should not have to edit it. If for some reason or another you still feel like it, you need to know that you can set additional .Rmd subdirectories, set another output file than the standard \versions file, and toggle the deletion of merged files after the knitting process ended here.

The \bib folder

The bibliography folder contains two files; packages.bib and references.bib. The former is automatically generated by the first code chunk in the index.Rmd file and cites the packages you have loaded when running your code chunks. You will not need to alter this.

On the other hand, the references.bib file is the place to dump the bibtex citations that you will cite in your thesis.

The \data folder

The data folder is the place to put all the data that you use in the code chunk of your analysis. Remember to keep it tidy so you can easily link data to outputs down the line such as graphs and tables.

The \figures folder

The figures folder will contain all the graphical elements that you may want to include in your thesis e.g. figures, graphs, or images. It also contains a file named SecretariatDocument.pdf that you will need to replace with the one that was handed to you by the PhD or Master’s secretariat. Remember to rename the file you got from the secretariat as SecretariatDocument.pdf. Otherwise {iheiddown} will not recognize it.

The \front-matter folder

The front matter folder contains the front matter of your thesis. This is where you will be able to edit the abbreviations part in the corresponding Latex file, the acknowledgments section or the abstract of your thesis in their respective .Rmd files.

The \versions folder

This is where you will find the pdf file after your thesis has been knitted by {iheiddown}.
