The isoviewer graphical user interface (GUI) provided by this package is based on the functionlity implemented by the isoreader package. The purpose of the GUI is two fold.

First and foremost, it is a learning tool to illustrate how to build literate RMarkdown data processing files for IRMS data using the underlying isoreader package as a unified interface for reading, converting and quickly visualizing various raw IRMS data file formats.

The second purpose is to provide an example for a web-based IRMS data repository that is easy to run on any computer/server completely platform-independent and open-source. The isoviewer package provides some rudimentary GUI modules that could be used in other more customized applications. However, while this example app is relatively light weight and does not use a database back-end, one could consider more elaborate use cases of the isoreader and similar packages as a programmatic interface to IRMS data that allows large scale parallel processing, reproducible aggregation and potentially sharing of years of accumulated data.


Since isoreader and isoviewer are still in development, they are not yet available on the Comprehensive R Archive Network (CRAN) but can be installed easily from GitHub using the devtools package:

install.packages("devtools") # only needed if you don't have this installed yet

Using the User Interface

Once isoviewer is installed, you can easily launch the user interface on your local machine by using the run function and providing the path to the directory where your data is stored (the data_dir parameter). Additional optional parameters control other aspects of the GUI and can be set as needed. See ?isoviewer::run for help. To run it as a local server accessible via your network, make sure to specify the correct host IP address and a fixed port (see ?shiny::runApp for details).

run(data_dir = ".")

Online Demo

An online demo of the isoviewer GUI is available on our server but has limited computational resources (i.e. could be slow).
