使用automap包进行交叉验证的问题

I want to do a cross-validation for the ca20-Dataset from the geoR package. With for example the meuse-dataset, this works fine, but for this dataset, I encounter a strange problem with the dimensions of the SpatialPointsDataFrame. Maybe you can try this for yourself and explain why the autoKrige.cv function does not work (I tried several nfold-values but this only changes the locations-value of the error message...):I want to do a cross-validation for the ca20-Da
