GSoC Proposal 2014: package bdvis: Biodiversity Data Visualizations

I am applying for Google Summer of Code 2014 again with “Biodiversity Data Visualizations using R” proposal. We are proposing to take package bdvis to next level by adding more functions and making it available through CRAN. I am posting this idea to get feedback and suggestions from Biodiversity Informatics community.

The rOpenSci projects aims to provide programmatic access to scientific data repositories on the web. A vast majority of the packages in our current suite retrieve some form of biodiversity or taxonomic data. Since several of these datasets have been georeferenced, it provides numerous opportunities for visualizing species distributions, building species distribution maps, and for using it analyses such...

Moving the North Pole to the Equator

I am still working with @3wen on visualizations of the North Pole. So far, it was not that difficult to generate maps, but we started to have problems with the ice region in the Arctic. More precisely, it was complicated to compute the area of this region (even if we can easily get a shapefile). Consider the globe, worldmap <- ggplot()...

After a colleague of mine requested an illustration of the aggregation technique that was part of an introduction to spatial data in R, I decided to revisit aggregation. The first article I posted here on the subject used data from London; this one is slightly different, using Twitter data aggregated to the state level in the USA. All example code...

Package rinat use case: map of iNaturalist project

iNaturalist projects are collection of records posted on iNatualist. Now that we have a R package rinat from rOpenSci I thought of playing around with the data. Here is a function I wrote, to quickly map all the records of a project using ggmap package. We can used get_inat_obs_project function from rinat package to get
