Error in tapply when running gbm.auto package

Question

I am trying to run the gbm.auto package with the dataset provided by the author. I am working on a Mac. After I run the gbm.auto function with the default settings, I get this error at the end of the fourth step (BRT 4 out of 4)

Error in tapply(z[i], list(X[xi], Y[yi]), fun) : total number of levels >= 2^31

and the following warning messages

1: attribute variables are assumed to be spatially constant throughout all geometries 
2: glm.fit: fitted probabilities numerically 0 or 1 occurred 
3: glm.fit: fitted probabilities numerically 0 or 1 occurred 
4: glm.fit: fitted probabilities numerically 0 or 1 occurred

Does anybody know how to solve it? Thank you!
