R Package

Species Sensitivity Distributions App

The Species Sensitivity Distributions shiny app is a webpage for interactively fitting species sensitivity distributions to concentration data. The user is able to select more than one distribution and plot the individual fits. The calculations are performed by the ssdtools R package, which also generates the plots and tables. The shiny app also provides the R code that was used to perform an analysis so the user can replicate it using an R script.

Yield per Recruit App

The Yield per Recruit shiny app is a webpage for interactively exploring the effect of various fish population parameters on the schedule, stock-recruitment relationship and yield. The calculations are performed by the ypr R package, which also generates the plots and table. Figure 1. A screenshot of the yield from the Yield per Recruit shiny app. The app can be viewed at https://poissonconsulting.shinyapps.io/ypr-shiny/. Creditation The app was developed by Seb Dalgarno

Tidal Predictions App

The Tide Predictions shiny app is a webpage for visualizing and downloading tide height data. The tide heights are calculated using the rtide R package. Currently, predictions are available for 637 US stations. Unfortunately, Canadian stations are not available under an open license. Stations can be selected by name or by clicking on a map. Figure 1. A screenshot of the stations map from the Tide Predictions shiny app.

Kootenay Lake Fish Movement App

The Kootenay Lake Fish Movement shiny app is a webpage to view detections of acoustically tagged Bull Trout and Rainbow Trout in Kootenay Lake from 2008 to 2014. Figure 1. A screenshot of the Kootenay Lake Fish Movement shiny app. The app uses data from the klexdatr R package. There are two approaches to visualizing the data: Movement by Individual Allows the user to view movements of individual fish over time by selecting a fish ID.

Calculating Water Quality Thresholds and Indices for British Columbia using R

The wqbc R package calculates water quality thresholds and water quality indices and plots water quality indices spatially and temporally for British Columbia. The package was written for the B.C. Ministry of Environment by Poisson Consulting. Ministry of Environment staff maintain the package. This vignette was primarily written by Colin Millar. Introduction The main function of the wqbc (water quality for British Columbia) package is to calculate the Canadian Council of Ministers of the Environment (CCME) water quality index (WQI) for water bodies in British Columbia, the procedure is set out in the CCME WQI (1.
