#NowWatching — @TrestleJeff, talking about {plumber} 🛠⚙️register.gotowebinar.com/register/55312…
#RStats #RStudio #Webinar
💬 "If you're aiming at humans only, you can build a shiny app. If you want machines to access your data, build an API"

💬 "And remember that any other language can access your R API. You're opening a lot of doors."

#RStats
Some important things to know when working with APIs:

🕸 About http requests : developer.mozilla.org/en-US/docs/Web…

🚀 About REST API : en.wikipedia.org/wiki/Represent…
💬 "With plumber, you can build an http API around your existing R code. You just need a little decoration."

📦 github.com/trestletech/pl…
💬 "You can then access this function through your browser, with query string syntax"

More about query string syntax : en.wikipedia.org/wiki/Query_str…
📈 Plumber is able to return other type of content, instead of JSON.

Here's an example with dygraphs and htmlwidget

They are called serializers : rplumber.io/docs/rendering…
🚀 Now, time to launch!
Now, what if {plumber} becomes the central point of the data science infrastructure?

-> Writing a plumber API before a Shiny App allows other languages to use this API, instead of just Shiny.

-> R Created models and data-wrangling which are totally portable
▶️ @TrestleJeff does a demo with an "emoji Browser", which shows an heatmap and a graph of emoji sent live.

💬 "Just imagine how painful it would be to write an heatmap in php" 😇
[Some tricks and tricks]

💬 "You can run {plumber} anywhere":

How to deploy {plumber}

▶️ rstudio connect rsconnect::deployAPI() — rstudio.com/products/conne…

▶️ digital ocean with do_provision() — digitalocean.com/?refcode=be73a…
[Some tricks and tricks]

▶️ {plumber} is now integrated in RStudio (see the dailies for more) : dailies.rstudio.com

▶️ swagger is supported, and are generated from the plumberfile : swagger.io
[Some tricks and tricks]

🐜 Debugging — You can debug API the very same way you would debug any R Code.

Use the swagger and `browser()` : stat.ethz.ch/R-manual/R-dev…
What's in the future ?

▶️ Async : github.com/trestletech/pl…

▶️ Testing

▶️ More docs : rplumber.io

▶️ Additional maintainers

#NowReading — Writing #RStats Extensions.
colinfay.me/writing-r-exte…
[Notes on terminology]
"A package is not a library."
Library refers to:
- "A directory into which packages are installed"
- "That used by the operating system, as a shared, dynamic or static library or (especially on Windows) a DLL, where the second L stands for ‘library’."
"Installation takes a source package and installs it in a library using R CMD INSTALL or install.packages."
"Source packages can be built. This involves taking a source directory and creating a tarball ready for distribution"

In the spirit of #EpiWritingChallenge, I thought I'd share some elements of my writing workflow in Rstudio and R Markdown. I'm changing this all the time and would love to hear about yours! You can find this example on my GH here: github.com/malcolmbarrett… #rstats 1/8
The best thing about markdown is the way you can intermingle text with code, but I often find I need to focus on the words. The first step for me is to zoom to the the source pane using ctrl-shift-1 #rstats 2/8
Then, I collapse everything using the fold fall keyboard shortcut, which is opt+cmd+o on Mac and alt+o on Windows. I only unfold the section I want to work on and focus on that #rstats 3/8

During our #webinar on the #MSSP proposed rule we had a Q&A with @Farzad_MD and @Travis_Broome. We're sharing the most asked questions and answers below.

See the full webinar here: register.gotowebinar.com/register/28290…

Q: Do "low-revenue" ACOs have to enter "Enhanced" track if they have prior experience?
A: No, a low-revenue ACO that is inexperienced with risk can be in the BASIC glide path for agreement period 1 and Level E for their second agreement. More nuanced if experienced with risk
Q: Do percentage regional benchmarks apply to new start ACOs? What does percentage benchmark mean?
A: Regional benchmarks will now start in agreement period 1 (35% for efficient, 25% for inefficient). Independent practices tend to be more regionally efficient!

Getting ready to teach dplyr joins to new #rstats users tomorrow, so naturally I productively procrastinated by getting to know the new gganimate. It is the coolest!
The readme is a great intro -- github.com/thomasp85/ggan…. I basically just replaced `+facet_wrap(~ key)` with `+transition_states(key)`.
I really like how easily the gganimate calls fit in with the ggplot pipeline. It's very clear @thomasp85 put a lot of thought and care into the API design.

Thread: Though there is lots of community interest in model-agnostic model explanations (eg. LIME), I’ve been interested in an explainer specific to random forests. Came across a great one here: github.com/MI2DataLab/ran… #rstats
To begin, train an RF model and run the explain_forest() function. #rstats
Next thing you know, a variety of “views” into the forest appear on your machine. Can explore interactions between metrics and variables. For more details, check out this vignette: rawgit.com/MI2DataLab/ran… #rstats

If you’re an academic you need a website so that people can easily find info about your research and publications. Here’s how to make your own website for free in an under an hour using the blogdown package in #Rstats [THREAD]
So why use blogdown? Sure, there are several free options available to start your own blog (e.g., Medium). However, you generally can’t list your publications or other information easily on these services. Also, who knows where these services will be in a few years?
There are also some great point-and-click services available (e.g., Squarespace). However, you need to pay about $10 a month for these services, and they’re generally not well suited for academic webpages.
