The team at rOpenSci and I have been working on a wrapper for the USA National Phenology Network API. The following is a demo of some of the current possibilities. We will have more functions down the road. Get the publicly available code, and contribute, at Github here. If you try this out look at the Description file for the required R packages to run rnpn. Let us know at Github (here) or at our website, or in the comments below, or on twitter (@rOpenSci), what use cases you would like to see with the rnpn package.

Method and demo of each:
Get observations for species by day
From the documentation:

This function will return a list of species, containing all the dates which observations were made about the species, and a count of the number of such observations made on that date.

Note, the data below is truncated for blogging brevity…
