replext_pgsql {mmirestriktor}

Launch Replext Simulation Shiny Application

Description

This function creates and launches a Shiny web application for running simulations related to constrained statistical inference in ANOVA and regression settings. The application allows users to set various parameters for replext_t1_c1 and replext_t2_c1 functions and view the resulting simulation data. The simulation is based on Vanbrabant et al. (2015). The app includes functionality to interact with a PostgreSQL database. The app includes a user interface for selecting simulation parameters and a server logic to process the simulation and handle user interactions, including saving and retrieving data from a database.

Usage

replext_pgsql(dbname, datatable, host, port, user, password)

Arguments

dbname

The name of the PostgreSQL database to connect to.

datatable

The name of the table in the database where the simulation results will be stored and retrieved.

host

The host address of the PostgreSQL database.

port

The port number for the PostgreSQL database connection.

user

The username for accessing the PostgreSQL database.

password

The password for the specified user to access the PostgreSQL database.

Details

The Shiny application consists of a user interface for setting simulation parameters and a server logic to process the simulations and save to PostgreSQL database. Users can select between different simulation settings (cell blocks), specify parameters, run the simulations, view the results in a table format, submit results to PostgreSQL database, and download the database table. The application also handles dynamic UI elements based on user selections and manages data downloads.

Value

A Shiny app object which can be run to start the application.
