I’ve worked for over 12 years in hydrology and natural hazard modelling and one of the things that still fascinates me is the variety of factors that come into play in trying to predict phenomena such as river floods.
I’ve recently released the new package ccafs, which provides accessto data from Climate Change, Agriculture and Food Security(CCAFS; http://ccafs-climate.org/) General Circulation Models (GCM) data.GCM’s are a particular type of climate model, used for weather forecasting,and climate change forecasting - read more athttps://en.wikipedia.org/wiki/General_circulation_model.
Do you fancy open data, R, and breathing? Then you might be interested in ropenaq which provides access to open air quality data via OpenAQ! Also note that in French, R and air are homophones, therefore we French speakers can make puns like the one in the title.
Our Community Call on Tuesday, March 7th, 8-9 AM PST, will cover “How to ask questions so they get answered! Possibly by yourself!”. Asking questions about programming is a skill you can develop - we’re not just born with it. The speakers will cover some of the background and skills you’ll need to increase your chances of having your questions answered by your peers or by a busy expert.
As a lab scientist, I do almost all of my experiments in microtiter plates. These tools are an efficient means of organizing many parallel experimental conditions. It’s not always easy, however, to translate between the physical plate and a useful data structure for analysis. My first attempts to solve this problem–nesting one ifelse call inside of the next to describe which well was which–were very unsatisfying.
For a fourth year running, we are excited to announce the rOpenSci unconference, our annual event loosely modeled on Foo Camp. We’re organizing #runconf17 to bring together scientists, developers, and open data enthusiasts from academia, industry, government, and non-profits to get together for a couple of days to hack on various projects and generally enrich our community. The agenda is mostly decided during the unconference itself.
Programmatic access to biodiversity data is revolutionising large-scale, reproducible biodiversity research. In the marine realm, the largest global database of species occurrence records is the Ocean Biogeographic Information System, OBIS. As of January 2017, OBIS contains 47.78 million occurrences of 117,345 species, all openly available and accessible via the OBIS API.
This week an update for xml2 and a new xslt package have appeared on CRAN. A full announcement for xml2 version 1.1 will appear on the rstudio blog. This post explains xml validation (via xsd schema) and xml transformation (via xslt stylesheets) which have been added in this release. XML schemas and stylesheets are not exactly new; both xslt 1.1 (2001) and xsd 1.0 (2004) have been available in browsers for over a decade.
A research project often starts with a bright idea and an initial commitment of volunteer time, or perhaps,a fixed term grant. But what happens after that initial activity? How can the project continue tosustain itself? (We define sustainability as the capacity to endure.
Making packages is a great way to organize R code, whether it’s a set of scripts for personal use, a set of functions for internal company use or a lab group, or to distribute your new cool framework foobar to the masses. There’s a number of guides to writing packages, including http://r-pkgs.had.co.nz/. As you develop packages there’s a number of issues that don’t often get much air time. I’ll cover some of them here.
