R commander not openning in Mac due to error in structure

Question

I have installed the new version of R along with the new version of XQuartz. After that, I have restarted my computer.

I am not being able to open R commander, the following message comes up:

When loading the Rcmdr package, the following alert comes up: Erro: package or namespace load failed for 'Rcmdr': .onAttach falhou em attachNamespace() para 'Rcmdr', detalhes: chamada: structure(.External(.C_dotTcl, ...), class = "tclObj") erro: [tcl] failed to allocate font due to internal system font engine problem.

My system is composed of:

macOS High Sierra 10.13.6

R version 3.5.1

XQuartz 2.7.11

Does anyone know what to do?

Answer 1

Had the same problem when working with the downscale.raster() function from " spatialEco ": Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") :[tcl] failed to allocate font due to internal system font engine problem.

Solved by installing the " tcltk2 " package and updating " spatialEco ".
