Previously on this blog we have discussed making geojson maps and uploading to Github for interactive visualization with USGS BISON data, and with GBIF data, and on my own personal blog. This is done using a file format called geojson, a file format based on JSON (JavaScript Object Notation) in which you can specify geographic data along with any other metadata.
In two the previous posts about geojson, I described how you could get data from the USGS BISON API using our rbison package, and from the GBIF API using the rgbif package, then make a geojson file, and send to Github. In both examples, the data were points. What about polygons? This is a relatively common use case in which an area is defined on a map instead of points - and polygons are supported in geojson. How do we do this with the R to geojson to Github workflow?
...Open access week is here! We love open access, and think it’s extremely important to publish in open access journals. One of the many benefits of open access literature is that we likely can use the text of articles in OA journals for many things, including text-mining.
What’s even more awesome is some OA publishers provide API (application programming interface) access to their full text articles. Public Library of Science (PLOS) is one of these. We have had an R package for a while now that makes it convenient to search PLOS full text programatically. You can search on specific parts of articles (e.g., just in titles, or just in results sections), and you can return specific parts of articles (e.g., just abstracts). There are additional options for more fine-grained control over searches like facetting.
...I attended the recent ALM Workshop 2013 and data challenge hosted by Public Library of Science (PLOS) in San Francisco. The workshop covered various issues having to do with altmetrics, or article-level metrics (ALM). The same workshop last year definitely had a feeling of we don’t know x, y, and z, while the workshop this year felt like we know a lot more. There were many great talks - you can see the list of speakers here. I was there representing rOpenSci as altmetrics is one of the types of data for which we make R libraries (rAltmetric for Altmetric.com data, and alm for the PLOS altmetrics data)....
With the US government shut down, many of the federal government provided data APIs are down. We write R packages to interact with many of these APIs. We have been tweeting about what APIs that are down related to R pacakges we make, but we thought we would write up a proper blog post on the issue.
NCBI services are still up! NCBI is within NIH, which is within the Department of Health and Human Services. Here is the message on the NCBI page:
...Just a quick note that the Task View we have been working on with others Web Technologies and Services is up on CRAN now. Find it here https://cran.r-project.org/web/views/WebTechnologies.html.
This is the first version - there are definitely changes to come. Changes are being suggested as I write this on Twitter…
The draft version of the task view is on Github here if you want to file an issue.
We use many packages to do stuff with the web like XML, RCurl, httr, RJSONIO, etc., and we create many packages that grab data from the web. So it made a lot of sense to work on this task view. We hope it is a good resource for everyone.
