Conditional variable importance error

[Christoph Ruehlemann]

Hi All,

I'm doing a Random Forest analysis (perturb = list(replace = TRUE), ntree = 1500, mtry = 3) using the cforest function from the library partykit with a large number of predictor variables (altogether 13) and want to determine conditional variable importances using the varimp function. However, I get this error:

Error in FUN(model = model, trafo = trafo, data = data, subset = subset,  : 
  NROW(Y) == length(ix) is not TRUE

Interestingly, when I do conditional = FALSE, everything works fine - no error. Does anyone know the error and know how to get rid of it?

Many thanks

Christoph
