Your Turn

  1. Create a new project. Don't worry too much about what's it called, etc because we'll only use this for a bit to demonstrate how RMarkdown works.

  2. Create a new RMarkdown file, setting the default output format as Word.

  3. Save your RMarkdown file as report.Rmd.

  4. Look through this RMarkdown file and make sure that you can identify the YAML, text sections, and code chunks.

  5. Click the Knit button and open the file that gets produced (report.docx).

I've noticed my document by default doesn't include a date and author - I can easily add in manually, but was wondering if it was a setting I should change in my Rstudio app?

Nevermind - figured out in the next lesson that the author was a case to fill when creating the document, and the date does appear automatically if the author is filled (seems like it is ommitted if the author is as well).

Glad you got it figured out!

David Keyes

Yup, you can definitely change it! I'll usually do HTML when I first start something because it's easiest. I'll then later change to a different format depending on what I need for my final deliverable.

Getting an error which says - Required package version could not be found: caTools 1.14 is not available. What do I need to update ?

David Keyes

Very odd. It looks like you need to update the caTools package. You can do that with this code:

install.packages("caTools")

Yeah, and you can even make multiple reports at once using RMarkdown! See this article explaining the process and this example of multiple reports we made for a client.

Hi David,

I was experimenting the formats that we could product upon knitting RMarkdown. However, I ran into some trouble while attempting to produce a PDF output.

The error message on the 'compile PDF' tab was — Unable to find specific LaTeX program 'pdfLaTeX' on system path.

Does this mean that I might have to additionally install other packages to enable this?

I think this means that RMarkdown is having trouble finding LaTeX, which it needs to compile your document into PDF. Can you please install tinytex using this code and then try again:

install.packages('tinytex')
tinytex::install_tinytex()

Please let me know if that works!
