Dear grass users,


since today I’ve the following problem:


starting rgrass7 package in R in the grass7 console I get the following error 


> library(rgrass7)

Lade n├Âtiges Paket: sp

Lade n├Âtiges Paket: XML

Error : .onAttach in attachNamespace() f├╝r 'rgrass7' fehlgeschlagen, Details:

  Aufruf: if (class(t0) != "try-error" && is.character(t0) && nchar(t0) >

  Fehler: Fehlender Wert, wo TRUE/FALSE n├Âtig ist

Fehler: Laden von Paket oder Namensraum f├╝r 'rgrass7' fehlgeschlagen


I tried the following options:


New installation of GRASS7 and R

Updated all packages in R

Installed the package rgrass7 on both sides, in an single R Session and also in 
the R Session inside the GRASS console,


But nothing works.


Is it possible to fix this?

Is there a way to set the namespaces for R or to repair them?


By the way: The same problem seems to be at v.krige in the GUI. I never get 
this addon to work and need to use the kriging interpolation methods.



Thank you for your help,


kind regards, Norbert Zirps.
