Problem explor() after updating Rstudio

[juliendgros]

Hello, Since the update to the latest version of Rstudio (I don't know if it's the cause, but it's concomitant), when I launch the explor() function, the window opens as before, but when I close it, R behaves as if it was not closed (impossible to run an instruction) and then crashes. I'm on version 4.0.3 of R. Am I the only one to have this problem? Thank you very much, Julien

Hi,

I can't reproduce the issue unfortunately (latest RStudio, R 4.2.0). Does the explor interface directly open in an RStudio window, or does it open first in the viewer pane ?

Thank you. The explor interface directly open in a Rstudio windows, as it did before. I replaced Rstudio with version 2022.02.3, there is the same problem. The following messages appear in red in the console when I lauch explor() :

After installing a slightly newer version of R (4.1) and updating the packages, the problem seems to be solved (there were conflicts between versions of the packages used by explor(), apparently). Thank you (and to Milan Bouchet-Valat for his live support).

You could try with the development version of explor, it should at least remove the Font awesome warnings, but I doubt it will solve the problem.

Otherwise maybe try to upgrade your R version if it is possible, at least to the latest R 4.0.x ?

No problem under R4.0.3. explor() opens a tab in my default web browser in my case, not the RStudio one. I noticed that when closing the explor tab, the shiny app is still running. I don't know if it's intended. Stopping the Shiny app in the console requires extra code IIRC, but that's overkill. I just pressed Esc key and the console is ready again. So, nothing unusual. May be there is some discrepancies with RStudio Shiny pseudo web browser. I never use it. If you want to force the app to use the system default web browser, you should add options in the shiny call. Replace https://github.com/juba/explor/blob/3c705b157357d02cbe6a26c8e7e28d0d26c09674/R/explor_multi_PCA.R#L345 by

options = list(launch.browser = TRUE)

Great job. Thanks for this package.
