R shiny app for Boat Run monitoring
I am very excited about R at the moment. Here is an example of an app I constructed for one of the long term monitoring projects at my full time place of employment.https://johnyagecic.shinyapps.io/BoatRunExplorer/ Related To leave a comment for the author, please follow the link and comment on their blog: AdventuresInData.

Automated Animated Tide Data
I developed an R script to retrieve NOAA PORTS data for the Delaware Estuary overnight and generate an animated water surface elevation plot. I hope to include this in a larger Delaware River Dashboard web page containing graphs of near real-time data.

Automated Animated Choropleth
Here’s an animated choropleth (graph using colored map shapes) of HUC8 watersheds in the Delaware River Basin showing water yield over a span of 20 days. The script is fully automated, pulling USGS gage data from NWIS, computing the water yield time series for each subwatershed, and generating the GIF. I hope also to include this in a Delaw...

Tidal Amplification – Chesapeake versus Delaware
In the Delaware Estuary, the tidal range at the mouth of the estuary becomes amplified, resulting in a larger range (difference between high and low tide water surface elevation) further up the estuary. One way to visualize this effect is via violin plots. The data below is from the NOAA PORTS system in the Delaware Estuary:River ...

Animated 3D Plot of Ammonia Toxics Criteria
In 2013, EPA published final national recommended water quality criteria for the protection of aquatic life from the toxic effects of ammonia in freshwater.http://www.epa.gov/wqc/aquatic-life-criteria-ammoniaThese criteria are a function of water temperature and pH, so that the criteria concentration value changes with changing pH and temperatur...

High Flows in Lower Columbia River near Portland, OR
After I completed the animated tidal water surface elevation plots for the Delaware Estuary, I looked for other systems with a good set of tidal observation stations. The Lower Columbia River near Portland, Oregon fit the bill. Using the NOAA PORTS stations, I set up near real-time animated plots of the Columbia. Throughout Dece...

Population Model Revisited
In a previous post I showed an animated age structure diagram depicting output from a simple population model written in Excel. Here is another version of that model written in R. One of the things I like about the R version is that I can post the animated .gif files directly into presentations without having to link to a video ho...
