rerun_analysis {shinymgr}

Re-run an previously executed shinymgr analysis

Description

Re-run an previously executed shinymgr analysis given an RDS file input from a previously saved analysis.

Usage

rerun_analysis(analysis_path)

Arguments

analysis_path

File path to the RDS file that stores a previously executed analysis.

Details

The function accepts a single argument that defines the file path to a saved shinymgr analysis (RDS file). This function will launch a shiny app, so can only be run during an interactive R session, in an R session with no other shiny apps running.

The app that is launched contains 2 tabs. The first tab is called "The App" and will be visible when the re-run function is called. It contains a header with the app's name and a subheading of "Analysis Rerun". Below that, a disclaimer appears, indicating the app was produced from a saved analysis. You may need to scroll down using the vertical scroll bar in the rendering betlow to see that below this disclaimer is a fully functioning, identical copy of the shiny app used to generate the saved analysis.

The second tab, called "Analysis Summary", simply displays the structure of the saved analysis, excluding any saved source code. The structure of the analysis gives a high-level summary, including the values that can be entered in the app to reproduce results.

Value

No return value, function launches shiny app

More Info

The rerun_analysis() function is described in the "analyses" tutorial.
