Create a Glossary in R Markdown - Yongfu's Blog. I was thinking about creating a glossary in bookdown and found out that there was already an issue about it. I like Yihui’s recommendation: use Pandoc’s definition lists. This was exactly what I had been doing, but I quickly found out that there was a major drawback – the definition lists won’t order alphabetically unless written in that way. So I wrote an R function to reorder the definition lists written in R Markdown. Note that this functions only works for R Markdown files containing defintion lists exclusively.
If the R Markdown files aren’t whole-definition-lists, the function will fail. Usage To order the definition lists alphabetically, simply put the Rmd file path in the function. Sort_def_list("glossary.Rmd") The output in PDF looks like this (I used the multicol package): Source Code. A new RStudio addin to facilitate inserting tables in Rmarkdown documents | Lorenzo Busetto Website & Blog. In the last months, I started increasingly using Rmd documents for preparing scientific reports, blog posts, etcetera.
While I really like the flexibility offered by the system, one thing that I thought could be improved is the support for easily inserting tables. So, “inspired” also by the recent addition of the excellent insert image addin in blogdown, I decided to give it a go and try to implement some kind of addin to facilitate table insertion in Rmd documents. After struggling a bit due to my rather nonexistent shiny skills, in the end I managed to obtain a “basic but useful” (IMO) addin. Let’s see how it works: Installation You can install the addin from GitHub with: # install.packages("devtools") devtools::install_github("lbusett/insert_table") Usage Upon installing, inserttable registers a new RStudio Addin (Insert Table) that can be used to easily insert a table in a Rmd document.
There are two main use modes: Launch the addin while the cursor is on a empty line That’s all!. 10 tips for making your R graphics look their best. So you've spent hours slaving over the code for a beautiful statistical graphic in R, and now you're ready to show it to the world. You might be printing it, embedding it in a document, or displaying it on the web. Don't do your graph a disservice by causing it to look anything less than perfect in its final venue. Here are 10 tips to help make sure your graphic will always look best. 1. Call the right device driver from a script It's tempting to just create graphics to the on-screen device (such as X11 on Linux or Quartz on MacOS) and then just use "Save As... " from the menu. The best practice is to create a script file that begins with a call to the device driver (usually pdf or png), runs the graphics commands, and then finishes with a call to dev.off().
Png(file="mygraphic.png",width=400,height=350)plot(x=rnorm(10),y=rnorm(10),main="example")dev.off() 2. If you plan to print your graphic, you want to use a vector-based format. 3. 4. 5. For PNG graphs, it's a bit tricker. Dev.off() 6. Tips and tricks for working with images and figures in R Markdown documents | Technical Tidbits From Spatial Analysis & Data Science. Writing reports in R Markdown allows you to skip painful and error-prone copy-paste in favor of dynamically-generated reports written in R and markdown that are easily reproducible and updateable.
R Markdown reports that are heavy on graphs and maps, though, can yield large HTML files that are not optimized for web viewing. R Markdown offers a wide range of functions and arguments for full control of image sizes but knowing how and when to use them can be daunting particularly given the differences in how external images are handled vs R-generated figures. We assembled this blog post to help guide you through image processing decision-making as you construct your own R Markdown reports. NOTE 1: This post is focused on the production of HTML documents and some of our conclusions and recommendations may not apply if you're using R Markdown to create a LaTeX document, PDF or Word document.

Ever wondered how to make an rmarkdown title dynamic? Maybe, wanted to use a parameter in multiple locations? Maybe wanted to pass through a publication date? Advanced use of YAML headers can help! Normally, when we write rmarkdown, we might use something like the basic YAML header that the rmarkdown template gives us. --- title: "My report" date: "18th April, 2017" output: pdf_document --- You may already know the trick about making the date dynamic to whatever date the report gets rendered on by using the inline R execution mode of rmarkdown to insert a value. --- title: "My report" date: "`r Sys.Date()`" output: pdf_document --- What you may not already know is that YAML fields get evaluated sequentially so you can use a value created further up in the params section, to use it later in the block. --- params: dynamictitle: "My report" reportdate: !
By doing this, you can then pass parameter values into the render() function when you want to generate a report.

Earlier this week, I spent a day chatting to folk from the House of Commons Library as a part of a bit of temporary day-a-week-or-so bit of work I’m doing with the Parliamentary Digital Service. During one of the conversations on matters loosely geodata-related with Carl Baker, Carl mentioned an NHS Digital data set describing the number of people on a GP Practice list who live within a particular LSOA (Lower Super Output Area).
There are possible GP practice closures on the Island at the moment, so I thought this might be an interesting dataset to play with in that respect. Another thing Carl is involved with is producing a regularly updated briefing on Accident and Emergency Statistics. Excel and QGIS templates do much of the work in producing the updated documents, so much of the data wrangling side of the report generation is automated using those tools. So what does an RStudio workflow have to offer? Like this: Like Loading... How to set up your own R blog with Github pages and Jekyll Bootstrap.
This post is in reply to a request: How did I set up this R blog? I have wanted to have my own R blog for a while before I actually went ahead and realised this page. I had seen all the cool things people do with R by following R-bloggers and reading their newsletter every day! While I am using R every day at work, the thematic scope there is of course very bioinformatics-centric (with a little bit of Machine Learning and lots of visualization and statistics), I wanted to have an incentive to regularly explore other types of analyses and other types of data that I don’t normally work with.
I have also very often benefited from other people’s published code in that it gave me ideas for my own work and I hope that sharing my own analyses will inspire others as much as I often am by what can be be done with data. Moreover, since I’ve started my R blog, I’ve very much enjoyed interacting more with other R-bloggers and R users and getting valuable feedback. Customizing your page cp .. Jupyter And R Markdown: Notebooks With R. When working on data science problems, you might want to set up an interactive environment to work and share your code for a project with others.
You can easily set this up with a notebook. In other cases, you’ll just want to communicate about the workflow and the results that you have gathered for the analysis of your data science problem. For a transparent and reproducible report, a notebook can also come in handy. That's right; notebooks are perfect for situations where you want to combine plain text with rich text elements such as graphics, calculations, etc. The topic of today's blog post focuses on the two notebooks that are popular with R users, namely, the Jupyter Notebook and, even though it's still quite new, the R Markdown Notebook.
You'll discover how to use these notebooks, how they compare to one another and what other alternatives exist. R And The Jupyter Notebook Running R in Jupyter With The R Kernel As described above, the first way to run R is by using a kernel. R Markdown: How to number and reference tables. R Markdown is a great tool to make research results reproducible. However, in scientific research papers or reports, tables and figures usually need to be numbered and referenced. Unfortunately, R Markdown has no “native” method to number and reference table and figure captions. The recently published bookdown package makes it very easy to number and reference tables and figures (Link).
However, since bookdown uses LaTex functionality, R Markdown files created with bookdown cannot be converted into MS Word (.docx) files. In this blog post, I will explain how to number and reference tables and figures in R Markdown files using the captioner package.

That is, each handout contained some standard text (including some R code) and some fields that were personalized for each participant (login information for our RStudio server).
I wanted to do this in RMarkdown so that the R code on the handout could be formatted nicely. Turns our this is a pretty straightforward task. All relevant files for this example can also be found here. This is a 20 x 2 csv file, an excerpt is shown below. Makefiles and RMarkdown | PirateGrunt. Quite some time ago (October 2013, according to Amazon), I bought a copy of “Reproducible Research with R and RStudio” by Christopher Gandrud.
And it was awesome. Since then, I’ve been using knitr and RMarkdown quite a lot. However, until recently, I never bothered with a makefile. At the time, I had assumed that it was something only available to people on *nix systems and back then I was developing exclusively on PC. I even wrote some R scripts that were more or less makefiles; reading the contents of a directory, checking for output and running render or knit or whatever. My workflow continued to evolve and get standardised, I moved to Linux and so I picked up Gandrud’s book again to review the bits about makefiles. I’m not sure when it was that I realized that RTools includes a make program for Windows, but I wish someone had told me that a couple years ago. So, enough preamble.

This afternoon I stumbled across this one weird trick an undocumented part of the YAML headers that get processed when you click the ‘knit’ button in RStudio. Knitting turns an Rmarkdown document into a specified format, using the rmarkdown package’s render function to call pandoc (a universal document converter written in Haskell).
If you specify a knit: field in an Rmarkdown YAML header you can replace the default function (rmarkdown::render) that the input file and encoding are passed to with any arbitrarily complex function. For example, the developer of slidify passed in a totally different function rather than render - slidify::knit2slides. I thought it’d be worthwhile to modify what was triggered upon clicking that button - as simply as using a specified output file name (see StackOverflow here), or essentially running a sort of make to compose a multi-partite document. via Software Carpentry For what it’s worth, my current YAML header for a manuscript in PDF is:
Make prettier documents by reusing chunks in RMarkdown | What You're Doing Is Rather Desperate. No revelations here, just a little R tip for generating more readable documents. Original with lots of code at the top There are times when I want to show code in a document, but I don’t want it to be the first thing that people see.
