RMixtComp does not work on windows 11

[Quentin62]

When running the following code on windows 11, it crashes or the session must be stopped. It does not happened on Linux.

The problem is the same with the examples from the documentation. Those examples are tested by the CRAN on a windows server 2022 (see config), and it works. So it seems that the problem is related to windows 11.

Data: prostate.csv

data <- read.table("~/Téléchargements/prostate.csv", sep = ";", header = TRUE)
z = data[,1]
data = data[,2:13]
head(data)

              EKG = "Multinomial", HG = "Gaussian", SZ = "Gaussian", 
              SG = "Gaussian", AP = "Gaussian", BM = "Multinomial")

algo <- list(nbBurnInIter = 50,
             nbIter = 100,
             nbGibbsBurnInIter = 50,
             nbGibbsIter = 10,

alternatives on windows 11

• Use online notebooks https://github.com/vandaele/mixtcomp-notebook
• Install windows subsystem for linux in order to use ubuntu on windows https://ubuntu.com/tutorials/install-ubuntu-on-wsl2-on-windows-10#1-overview
• Use docker to run rstudio in an ubuntu container on your computer ( cf. https://rocker-project.org/images/versioned/rstudio.html) Install docker, then in a terminal, run docker run --rm -ti -e PASSWORD=mixtcomp -p 8787:8787 rocker/rstudio In a browser, open http://localhost:8787/ username: rstudio password: mixtcomp
