Hi, I have a issue loading Rcmdr today. It is very strange, as I could get it to work last week on the same computer. I have tried restarting the computer, and re-installing R and XQuartz, but nothing changes. This is what I get: sessionInfo() R version 3.2.4 (2016-03-10) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under: OS X 10.11.4 (El Capitan) locale: [1] fr_FR.UTF-8/fr_FR.UTF-8/fr_FR.UTF-8/C/fr_FR.UTF-8/fr_FR.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base BQ_BEGIN library(Rcmdr) BQ_END Le chargement a n?cessit? le package : splines Le chargement a n?cessit? le package : RcmdrMisc Le chargement a n?cessit? le package : car Le chargement a n?cessit? le package : sandwich Error : .onAttach a ?chou? dans attachNamespace() pour 'Rcmdr', d?tails : appel : structure(.External(.C_dotTclObjv, objv), class = "tclObj") erreur : [tcl] invalid command name "image". De plus : Warning message: In fun(libname, pkgname) : couldn't connect to display ":0" Erreur : le chargement du package ou de l'espace de noms a ?chou? pour ?Rcmdr' Would you have a idea of what could be wrong ?
