Package 'pathlab'

Title: Point-and-Click PLS-SEM, CB-SEM, Statistics and More in the Browser
Description: PathLab SEM runs on your own computer and opens in your web browser, in the way 'bibliometrix::biblioshiny()' does. You draw a path model on a canvas and estimate it with 'seminr' (PLS-SEM), 'lavaan' (CB-SEM) or 'cSEM' (GSCA). The app also offers statistics with the 'jmv' engine, qualitative comparative analysis, latent profile and class analysis, machine learning, bibliometrics, and text and qualitative data analysis. Your data never leave your computer: start the app with run().

Repositories to install from (CRAN by default).

Start PathLab SEM

Description

Starts PathLab SEM on this computer and opens it in your web browser, in the way bibliometrix::biblioshiny() does. Your data stay on your computer: the app runs in a separate R process that only this computer can reach (127.0.0.1).

Usage

run(port = NULL, host = "127.0.0.1", launch.browser = TRUE, viewer = FALSE, background = FALSE, timeout = 180)

Arguments

port

Port number. NULL (default) picks a free port.
host

Address to listen on. Keep "127.0.0.1" so that only this computer can open the app.
launch.browser

Open the app (in the web browser, or the Viewer pane with viewer = TRUE).
viewer

Open the app in the Viewer pane of RStudio or Positron instead of the web browser.
background

FALSE (default): R waits while the app runs; press Esc (RStudio) or Ctrl+C to stop it. TRUE: the app keeps running while you use R; stop it with stop_app().
timeout

Seconds to wait for the app to start.

Details

Save your work with the app's Save button: a project lives in memory while the app runs, and saved .plj project files open again later. Run check_setup() if the app does not start.

In RStudio the Addins menu has Start PathLab SEM, Start PathLab SEM in the Viewer and Stop PathLab SEM. On RStudio Server and Posit Cloud the app opens at the address RStudio forwards to it.

Value

The address of the app, invisibly.

## Not run: 
pathlab::run()

## End(Not run)
