dataView

Data View is a simple shiny app that allows one to emulate 'extending' the 4-pane interface of Rstudio. It can be launched from either a separate Rstudio window, or directly from an R-REPL in a console (recommended).

To launch navigate to the app directory and run

shiny::runApp()

By default, it will show the Theoph dataset. To re-render currently, it simply monitors the app directory for a file called data.rds (which is created by default and is Theoph). To overwrite Theoph and use your data, one can simply call the command

saveRDS(data_to_view, "<path-to-dataView>/data.rds")

It looks like:

Functionality

Current functionality is limited to sorting (color changes on sorted column) as well as basic filtering via Search

note about crashing

If you feed it bad data, it will likely crash. If it becomes unresponsive, just kill the R session and open a new one.

TODO:

• Add button to uncheck all columns
• Add sleep so it consumes less resources will still remaining active - though polling once per second should have minimal CPU load
• Add a file navigator to allow selection of other data in the file-system
• Add ability to watch multiple datasets/folder and render any/all in a folder

Known bugs:

For columns of type hms will show the underlying value (eg seconds since midnight), rather than the human readable printed result (eg 27000 rather than 7:30:00)
