Phaedra is an open source platform for data capture and analysis of high-content screening data. With the release of Phaedra 1.0.2, we are taking another step towards our goal of unprecedented flexibility in supported setups, ranging from a single small Mac desktop to a cloud-based infrastructure with multiple servers and an array of mixed Windows/Mac/Linux clients. The initial release of Phaedra supported only the Windows platform. Update 1.0.1 introduced Phaedra on the Mac and Linux desktops, and allowed you to deploy a DataCapture server on Linux servers as well.
Motivation Have you ever had the feeling that the creation of your data analysis report(s) resulted in looking up, copy-pasting and reuse of code from previous analyses? This approach is time consuming and prone to errors. If you frequently analyze similar data(-types), e.g. from a standardized analysis workflow or different experiments on the same platform, the automation of your report creation via an R ‘template’ package might be a very useful and time-saving step.
ShinyProxy is a novel, open source platform to deploy Shiny apps for the enterprise or larger organizations. Since our last blog post ten new releases of ShinyProxy have seen the light, but with the 1.0.2 release it is time to provide an overview of the lines of development and advances made. Scalability ShinyProxy now allows to run 1000s of Shiny apps concurrently on a Docker Swarm cluster. Moreover, ShinyProxy will automatically detect whether the Docker API URL is a Docker Engine API or a Swarm cluster API.
Organising useR!2017 was a challenge but a very rewarding experience. With about 1200 attendees of over 55 nationalities exploring an interesting program, we believe it is appropriate to call it a success - something the aftermovie only seems to confirm. Behind the Scenes To give you a glimpse behind the scenes of the conference organization, Maxim Nazarov held a lightning talk on ‘redmineR and the story of automating useR!
In our last blog post we mentioned the need people felt to integrate Shiny apps in content management systems like Drupal. Release 0.7.8 added one extra feature in this respect so people could also include ShinyProxy hosted Shiny apps in external iframes. It also kicked-off our effort to support service scalability and ever more complex apps. In the scalability area, we introduced facilities to manage and set memory limits on individual Shiny applications.
Since the last release (see this blog post), we received two interesting use cases for which we did not imagine ShinyProxy would be used. First of all, we received a request to support other authentication methods than LDAP authentication. Whereas ShinyProxy is currently used primarily by larger organizations and companies that typically work with LDAP-based authentication systems, it seems people appreciate the elegance of the framework also for more small-scale use.
Our previous post on the how and why of ShinyProxy triggered a lot of encouraging reactions. Here’s our favorite: Indeed choosing for Docker opens a world of possibilities for ShinyProxy and making you no longer dependent on a particular version of R or shiny is only one of the advantages. We also received a number of useful suggestions and decided to quickly release the new features and fixes as version 0.
ShinyProxy is a novel, open source platform to deploy Shiny apps for the enterprise or larger organizations. Why is this needed? There is currently no valid open source alternative that offers this functionality. What does it offer? authentication authorization securing traffic with TLS/SSL usage statistics scalability This is free and open source, is there also a paying and proprietary version?
The knarrs of Open Analytics have left the port of Antwerp on their way to Denmark. What will our delegation bring to Aalborg besides our loyal sponsorship? Tuesday For starters we’ve just released a Dockerfile Editor which may be particularly useful for Dirk Eddelbuettel’s tutorial on Docker on June 30. An overview of all tutorials can be found here. Wednesday On the first day of the conference Willem Ligtenberg will present at 16:00 on how to use databases in R without a line of SQL with Rango.
In the last two years, software development had taken a step forward with the advent of the Docker. For the uninitiated, a Docker is a tool that automates the deployment of applications by packaging them with their dependencies in a virtual container, eliminating the need for virtual machines. Docker has streamlined the process of application development on Linux servers, and Open Analytics has streamlined the creation of Docker files with Architect’s new Dockerfile Editor.
