With dozens of RStudio Convention movies now readily available on the internet, it’s difficult to know the place to begin. I hope this look at some of my favorites will support get you began!
Mistake messages in R
I could probably enjoy Jenny Bryan instruct details entry (oh, that appears to be like attention-grabbing, maybe I want to attempt typing in a thousand rows . . . . ). But in this keynote, she tackles a substantially additional compelling subject: dealing with faults in R. There is a ton of useful suggestions here, which she shares in an engaging, relatable way. A person takeaway: Attempt the equivalent of a reboot—restart your R session! (I’ve been accomplishing that substantially additional often because returning from the conference.) Video: Item of kind ‘closure’ is not subsettable.
New attributes in RStudio
Pondering what attributes are coming to the upcoming model of RStudio desktop? RStudio’s Jonathan McPherson outlined many, which include contemporary-period spell check out (at previous), improved cloud usability on iOS, and additional monitor-reader accessibility for visually impaired users—something that also improves keyboard navigation for all users. Video: RStudio one.3 Sneak Preview.
Point out of the tidyverse
RStudio Chief Scientist Hadley Wickham reviewed previous year’s highlights from the tidyverse and this year’s strategies for even more progress, but he was also quite forthright in talking about some current missteps.
In particular, he acknowledged that the initial rollout of “tidy evaluation” launched with a fairly tricky-to-grasp syntax and an unreasonable expectation that users would want to learn the specific computing principle powering it. It turned out that numerous users didn’t care about the mechanics powering incorporating the tidyverse into their possess custom made functions they just preferred to produce their code. Considering that then, tidy eval syntax has been adjusted to additional comprehensible
Wickham also outlined how tidyverse package authors will support users improved have an understanding of the lifecycle of more mature functions and if/how some functions may possibly be deprecated. Video: Point out of the tidyverse.
Styled text with ggtext
Claus Wilke gave an overview of the ggtext package in this quickly-paced presentation, demonstrating how to customize ggplot visualizations with colored text, visuals on axes, and additional. He also stated the package’s existing restrictions. Video: Spruce up your ggplot2 visualizations with formatted text.
Down below, you can also enjoy my Do More With R tutorial on a person way to use ggtext: incorporating colour to ggplot text. (Or read through the companion report.)
What you didn’t know about R’s scales package
I’ve made use of scales package functions this sort of as
greenback() to include commas or greenback indicators to a vector of numbers, but I never ever genuinely explored the package even more. Turns out that was my loss. At this presentation, details scientist Dana Seidel showed that scales does a ton additional than structure numbers. A person tip: The
show_col() function allows you easily see how various colours and palettes look. Video: The minor package that could: Using visualizations to the upcoming level with the scales package.
Customizing Shiny apps and R Markdown
Greater spaghetti plots working with brolgar in R
What do you get when you have a load of products plotted above time? That details kind is recognized as longitudinal, and visualizing it can often close up seeking like a pile of spaghetti. To support solve this difficulty, Nicholas Tierney at Monash College created the brolgar package (enjoy the presentation if you’re thinking why that title) to summarize, visualize, and normally have an understanding of this sort of details. Video: Making improved spaghetti (plots): Checking out the men and women in longitudinal details with the brolgar package.
Dataviz ideal (and worst) procedures
This was not R-distinct, but College of Pennsylvania dataviz expert Will Chase gave an engaging, opinionated speak on how to “take your charts from drab to fab.” A person tip: “White space is like garlic — take as substantially as you think you will need and triple it.” Video: The Glamour of Graphics.
R Markdown to its restrictions
There is a ton additional a person can do with R Markdown than I thought. And the enjoyable-as-effectively-as-academic Teacup Giraffe website pushes the restrictions. In addition to making the most of a look at the Teacup Giraffe web page, this presentation by neuroscience Ph.D. college student Desiree De Leon incorporates some simple suggestions for strengthening your possess R Markdown paperwork. Video: Of Teacups, Giraffes, & R Markdown.
And speaking of acquiring additional out of markdown, RStudio’s Yihui Xie experienced a different speak demonstrating how to produce numerous additional file forms than just HTML or PDF from an R Markdown doc. Video: A person R Markdown Doc, Fourteen Demos.
3D visualizations in R
I’d been resisting razzle-dazzle all-around the rayshader package for awhile. Did I genuinely will need to flip ggplots into 3D visualizations and animate them? But I’m glad I went to creator Tyler Morgan-Wall’s presentation, due to the fact the package is rather cool—even if I’m not confident nonetheless how I’d use it in my possess perform.
Morgan-Wall showed how to flip a traditional graphic into a 3D visualization and animation with pretty minor code. He also showed some current package enhancements that make some graphics additional visually placing. In this situation, looking at the animated illustrations is a ton improved than trying to read through about them. If you’re at all fascinated in this package, it’s well worth watching the presentation. Video: 3D ggplots with rayshader.
Accelerating analytics in R
The Apache Arrow task is a multi-language standard for in-memory details aimed at interoperability and large performance. Arrow has been executed in R with the arrow package. Ursa Labs Engineering Director Neal Richardson outlined the standing of Arrow in R, which include the means to question a listing of information working with dplyr syntax with no obtaining to load that details into memory, as effectively as some future attributes. Video: Accelerating analytics with Apache Arrow.
list-columns in details.desk
If you have found the heated discussions on social media, you may well think that tidyverse and details.desk are in two opposing camps. But whilst every single has its enthusiasts, there are an expanding range of folks who use each. Utah Point out Research Assistant Professor Tyson S. Barrett is a person, and he introduced details.desk to RStudio Convention with a speak on working with advanced list-columns with details.desk and tidyverse functions. A person attention-grabbing tip: If you’re becoming a member of a advanced details established, nesting all of the columns you’re not becoming a member of on can support protect against faults.
Barrett also stated his tidyfast package, which has a streamlined “translation” of details.desk code to tidyverse-like functions. (It’s equivalent to dtplyr but doesn’t use “lazy” details sets.) Regrettably, this session movie sometimes obscures some of the code and graphs staying demonstrated. If you enjoy this a person, I suggest seeking at the slides individually they’re readily available at Barrett’s web page. Video: Record-columns in details.desk: Minimizing the cognitive & computational load of advanced details.

Bonus: RStudio Convention 2020 lightning talks
There were being a ton of attention-grabbing lightning talks, but a handful of stood out in component for the cool sites and packages staying demo’d as effectively as the shows themselves.
RStudio intern Maya Gans showed a drag-and-fall interface for tidyverse tasks this sort of as reworking, summarizing, and plotting details. It’s an attention-grabbing way to instruct tidyverse ideas right before learners have to learn real code. Video: TidyBlocks: working with the language of the tidyverse in a blocks-dependent interface. Web site: TidyBlocks.tech.
The nevertheless-experimental livecode package allows you are living code a demo and have it appear on attendees’ possess units in in the vicinity of serious time. College of Edinburgh lecturer Colin Rundel describes why you’d want to do that and how it works. Video: `livecode`: Broadcast your are living coding classes from and to RStudio.
Data science for software package engineers: Busting software package myths with R showcased a web page built to instruct stats to software package engineering learners with pertinent complications like: Does examination-pushed software package strengthen top quality? Does snooze deprivation make programmers additional or much less powerful? When will that task be concluded? Yim Register showed a bit of the website, but you can also check out out all the lessons at Data Science for Software package Engineers.
Bonus: RStudio Convention 2020 keynotes
RStudio founder and CEO J.J. Allaire discussed the point out of open supply software package, how it’s attainable to fund open supply attempts, and the company’s move to come to be a licensed reward company. Video (presentation only, not subsequent Q&A): Open Source Software package for Data Science.
Each individual time I see Martin Wattenberg and Fernanda Viegas speak, I go away sensation grateful that I’ve obtained a work that allows me peek into the perform and ideas of some supersmart folks. Co-leaders of Google Brain’s PAIR (Individuals+AI Research), the two discussed a range of their projects on matters like comprehending algorithm bias. Several of the projects they discussed are readily available to the public. Video: Data, visualization, and building.
A final be aware: With a number of tracks going on at the moment, I missed a ton of excellent talks. I also attended other superior ones that didn’t make the list due to the fact I didn’t want this report to get way too long. For example, how Affiliated Push uses R (Larry Fenn), hitting R a million moments a day at T-Mobile (Heather Nolis and Jacqueline Nolis), and tuning versions with the tune and workflow packages (Max Kuhn).
