R 3.5.2 now available

R 3.5.2, the latest version of the R language for statistical computation and graphics from the R Foundation, was released today. (This release is codenamed "Eggshell Igloo", likely in reference to this or this Peanuts cartoon.) Compared to R 3.5.1, this update includes only bug fixes, so R scripts and packages compatible with R 3.5.0 or R 3.5.1 should work without modification.

Installers for R on Windows and Debian Linux are available now; other platforms should be available from CRAN within the next few days. If you want to see the full list of fixes, check out the announcement from the R Core Group at the link below.

AzureStor: an R package for working with Azure storage

by Hong Ooi, senior data scientist, Microsoft Azure

A few weeks ago, I introduced the AzureR family of packages for working with Azure in R. Since then, I’ve also written articles on how to use AzureRMR to interact with Azure Resource Manager, how to use AzureVM to manage virtual machines, and how to use AzureContainers to deploy R functions with Azure Kubernetes Service. This article is the next in the series, and covers AzureStor: an interface to Azure storage.

The Resource Manager interface: creating and deleting storage accounts

AzureStor implements an interface to Azure Resource Manager, which you can use manage storage accounts: creating them, retrieving them, deleting them, and so forth. This is done via the appropriate methods of the az_resource_group class. For example, the following code shows how you might create a new storage account from scratch.

library(AzureStor)

# get the resource group for the storage account
rg <- AzureRMR::az_rm$
    new(tenant="{tenant_id}", app="{app_id}", password="{password}")$
    get_subscription("{subscription_id}")$
    get_resource_group("myresourcegroup")

# create the storage account
# by default, this will be in the resource group's region
rg$create_storage_account("mynewstorage")

Without any options, this will create a storage account with the following parameters:

  • General purpose account (all storage types supported)
  • Locally redundant storage (LRS) replication
  • Hot access tier (for blob storage)
  • HTTPS connection required for access

You can change these by setting the arguments to create_storage_account(). For example, to create an account with geo-redundant storage replication and the default blob access tier set to “cool”:

Because it's Friday: CGI you never knew was CGI

Computer-generated imagery in movies has gotten so good these days, much of the time you don't even realize it's there. You probably never noticed how Michael Cera's physique had been altered, or how Lost in Translation used motion capture technology from the future.

That's all from the blog team for this week. Have a great weekend, and see you next week!

How to deploy a predictive service to Kubernetes with R and the AzureContainers package

by Hong Ooi, senior data scientist, Microsoft Azure

It's easy to create a function in R, but what if you want to call that function from a different application, with the scale to support a large number of simultaneous requests? This article shows how you can deploy an R fitted model as a Plumber web service in Kubernetes, using Azure Container Registry (ACR) and Azure Kubernetes Service (AKS). We use the AzureContainers package to create the necessary resources and deploy the service.

Fit the model

We’ll fit a simple model for illustrative purposes, using the Boston housing dataset (which ships with R in the MASS package). To make the deployment process more interesting, the model we fit will be a random forest, using the randomForest package. This is not part of R, so we’ll have to install it from CRAN.

data(Boston, package="MASS")
install.packages("randomForest")
library(randomForest)

# train a model for median house price
bos_rf <- randomForest(medv ~ ., data=Boston, ntree=100)

# save the model
saveRDS(bos_rf, "bos_rf.rds")

Scoring script for plumber

Now that we have the model, we also need a script to obtain predicted values from it given a set of inputs:

How to give money to the R project

by Mark Niemann-Ross, an author, educator, and writer who teaches about R and Raspberry Pi at LinkedIn Learning

I spend a LOT of time at r-project.org, in particular the sections for documentation and CRAN. But I hadn’t spent much time in the other areas: R Project, R Foundation, and links. When I recently wandered into the foundation area, I discovered something worth talking about: donations to the R Foundation.

I benefit from the work of the R Foundation. They oversee the language, but also encourage a healthy ecosystem. CRAN happens because of them. Updates to R happen because of them. useR! happens because of them. Every day, you and I are the recipients of some part of their time.

The least we can do is show them some appreciation. If you point your web browser at https://www.r-project.org/foundation/donations.html you’ll find a convenient (and surprisingly inexpensive) place to express your appreciation. As an individual, you can send these kind folks twenty-five euros to tell them you’re in favor of what they do.

You can send them more if you like. You can make your twenty-five euros an annual event. If you’re an institution, you can give 250 euros. If you’re really suave and sophisticated, you can give 500 euros. I suspect you could give more, but you may have to warn the R Board of Directors so they aren’t wondering what you’re up to. (kidding!)

Best of all – for your minimum of twenty-five euros you get listed on the R Donors Site. Look close – you’ll even see my name listed amongst the R glitterati.

Tax Deductible?

For those of us in the United States, donations to charitable organizations are tax deductible. However, The R Foundation is not recognized as such in the US. But take heart — The Society of Indian Academics in America has stepped in to provide a method for earmarking donations — and making donations deductible. Look at the very bottom of the foundations donor page for details on how to make this happen.

Take Action

Calculate the difference in time spent between working with R — and working without R — then divide twenty-five euros by that amount of time. If you’re like me, that becomes a pretty good value. I think it’s well worth the time to make a donation and keep the R Foundation feeling appreciated.

Reflections on the 10th anniversary of the Revolutions blog

On December 9 2008, very nearly ten years ago, the first post on Revolutions was published. Way back then, this blog was part of a young startup called Revolution Computing, which later became Revolution Analytics. (That name persists to this day in the URL of this blog.) The idea at that time was to introduce the world to a wonderful but little-known statistics environment called R, by sharing news and applications of R to the broader data analysis community, along with tips and tricks for those that had already discovered R.

Since then, this blog has seen several waves shaking up the industry, from big data to data science, predictive analytics and machine learning, cloud computing and -- lately -- artificial intelligence. It's seen rising stars become leaders, new players become standards, and industry stalwarts enter the fray. And R has been there through it all.

I'd like to thank the organizers of the amazing SatRDays DC conference last weekend for allowing me to take some time at that event to reflect on the past 10 years of this blog, the R community, and how they intersected. You can see the video of the talk here, starting at the  2hr 19 minute mark. (That's a Facebook video and they don't support embedding, sadly.) I've also embedded the slides below: they don't mean much without the talk track, but you can use them to appreciate Ashely McNamara's gorgeous art.

Oh, and here are links to the posts mentioned:

It's been an amazing 10 years. I'd like to thank my various managers over the years for supporting me in the blog, all of my guest bloggers and most of the commenters (but not the trolls), and especially you, dear readers, for making this all worthwhile. Blogging has been a big part of my life, and I look forward to being able to continue the tradition in the future as well.

Happy 10th birthday, Revolutions!

Because it's Saturday: Go Your Own Way

I was delivering a workshop for AI Live yesterday so I didn't get the chance to do my Friday post, but I'm here at SatRDays DC and the playlist on the audio while we're waiting for things to start is amazing. Fleetwood Mac's Go Your Own Way just came on, which reminded me of this fascinating episode of Song Exploder where Lindsey Buckingham relates the story behind the song and how the musical components were layered together to crate the 1976 classic. 

We'll be back next week -- have a great weekend!
