Using R with the Stanford Digital Repository

In honor of the useR! 2016 Conference taking place this week, we wanted to outline ways researchers can use the Stanford Digital Repository to power their R visualizations.

The Stanford Digital Repository allow Stanford researchers and affiliates to deposit research data for preservation, access, and discovery. Data deposited in the repository is citable and from which the original content can be downloaded. The data is then made available through open web standard services for consumption. For example, images in the repository are delivered by a IIIF-compatible service, geospatial data are served out as Web Mapping Services (WMS) and Web Feature Services (WFS), and generic files are all served through HTTP.

R users can take advantage of these web services and the data being served out.

SDR Deposit of the Week: Liquid explosions

When Stanford Digital Repository staff found out someone was depositing research data about using x-ray lasers to explode jets of liquid, I have to admit there was a bit of excitement. Researching explosions (even on a small scale) sounds like an immense amount of fun. But Stanford researcher Claudiu Stan and his colleagues were doing way more important things out at SLAC than just having fun. They were performing serious research into fluid dynamics.

Hacking the David Rumsey Center (Part 2)

About this series

Over the next few weeks I will post a series of brief step-by-step "how-to" tutorials on making use of digital resources from the David Rumsey Map Center and Collection, that I presented in my "Hacking Rumsey" talk, presented at the opening events for The David Rumsey Map Center, at Stanford University Library.

We're starting small, with the easiest tools (like the David Rumsey Map Collection MapTab Chrome Browser Plug-in, which I covered in a previous post) that appeal to the most people, first. Eventually we will work our way up through more complex use of the collections and tools available from The Stanford University Library.

SDR Deposit of the Week: Earthworks in action against cholera

Inquiry from a hot zone

In late March of 2016, Frederic Ham, a geospatial analyst for Medecins Sans Frontieres (MSF, also know as Doctors Without Borders) contacted Stanford University Libraries (SUL) looking for information. He needed data to help him create maps so that MSF could better plan their response to a current cholera outbreak in Zambia. He’d found what he wanted via SUL’s geospatial data portal, Earthworks, but wasn’t able to access it due to licensing restrictions. Was there any way we could help?

SDR Deposit of the Week: Improving educational equity

May 2, 2016
by Regina Lee Roberts
Educational opportunity is an important issue in a democratic society. In the United States, measuring educational achievement and opportunity is complex because the public education system is diffuse. Funding for public education depends on a combination of local, state and federal governing bodies. The variations in funding and community level support for public education and standardized testing makes comparisons and analysis across the U.S. an arduous task. 
 
This is why the Stanford Digital Repository (SDR) deposit of the week is critically important to note. Stanford University Professor, Sean Reardon and his colleagues have just deposited the Stanford Education and Data Archive (SEDA) into the SDR for long term preservation. This is a data set that includes 215 million test scores and tackles the difficulty of comparing test score data from every public elementary and middle school in the United States for a period of 5 years, (2009-2013). What's brilliant about this collection of data is that, Reardon and his team developed a method to equate the scores across states for comparison enabling a whole new set of questions on educational opportunity to be answered, new stories to be told, and new questions to be raised.

SDR Deposit of the Week: Facilitating reproducibility

March 16, 2016
by Amy E. Hodge

Many scientists are making the reproducibility of their research a much higher priority these days than they used to. But it's a time consuming task, which means that many are searching for tools and workflows to help facilitate their efforts.

Hatef Monajemi, a PhD student in Civil and Environmental Engineering, and his PhD advisor Professor David L. Donoho, have developed a new piece of software that can make reproducibility an easier goal to achieve. His new software is called Clusterjob (CJ). This software can be used to develop reproducible computational packages and make the generation of data for a research study fully reproducible. CJ is an open-source software available on GitHub.
