shinyrems

shinyrems is an app that allows you to download, clean, visualize and analyze data from the Environmental Monitoring System (EMS) database. Create plots and view water quality data with BC aquatic life water quality guidelines.

⚠️ Package Warning

As of March 2026, the B.C. government has launched a new water quality monitoring database Environmental Monitoring Data System (EnMoDs) as a replacement for EMS. **Theshinyremsapplication relies on EMS data and is current to February 26, 2026. More recent data will not be accessible.**

Usage

See the User Guide for a more detailed explanation of app usage.

ShinyRems app can be run with various EMS datasets that must be downloaded and stored on the user’s computer. Prior to app startup, you will be prompted to download data if required and you will be notified if data updates are available.

There are six possible run modes corresponding to different datasets:

• ‘demo’ - uses a demo dataset that requires no download of EMS

• ‘2yr’ - uses most recent 2 years of EMS data
• ‘4yr’ - uses most recent 4 years of EMS data
• ‘historic’ - uses historic EMS data (1965 - (Current Year - 2

• ‘all’ - uses combined “2yr” and “historic” EMS data
• ‘upload’ - allows user to upload their own data following correct

To select a run mode, provide the value (as it appears above) to shinyrems::runemsapp(). For example, type the following into your R console:

r
select historic run mode
shinyrems::runemsapp("historic")
select upload run mode
shinyrems::runemsapp("upload")
"2yr" run mode is the default and will be selected if no other value is provided
shinyrems::runemsapp()
