It is no more possible to run the basic "Tutorial to use the stylometric tools of the Stylo R package into TXM":
https://groupes.renater.fr/wiki/txm-users/public/tutorial_to_use_stylo_into_txm

When installing the stylo package, we get the following stacktrace:

Exécution de session1.R…

Solution 1¶

• use "https://cloud.r-project.org" as default packages repository
• add the new R preference : "packages repository"

Not enough :

Warning: unable to access index for repository https://cloud.r-project.org/src/contrib:
  les routines internet ne peuvent pas être chargées

Solution 2¶

Open the R package repository dialog box or open a SWT dialog box (clone of the R dialog box)
