[R] cannot load rcmdr

[Mickael Vieira Da Silva]

After install the package RCMDR, I try to load it and it always apears the same error message:



Error : .onAttach failed in attachNamespace() for 'Rcmdr', details:
  call: Commander()
  error: could not find function "assignInMyNamespace"
Error: package/namespace load failed for 'Rcmdr'



I have the R version 2.14.2
the same error apears with a newest version

How can I solve this problem?

best regards
