I'm also trying to use the kennard-stone algorithm in the soil.spec package for my dataset, (to generate a training and test set from the data, based on this algorithm, because it's the most commonly used and well-performing algorithm in QSAR studies) but it's generating an error:
> ken.sto(mydataIN) Error in ken.sto(mydataIN) : subscript out of bounds My data is a 42 row by 6 column all numerical (except header) matrix of the format: id x1 x2 x3 x4 y1 2 66.7 7.71 0.079 4.58 3.0792 13 79.7 9.57 0.100 4.82 2.8451 5 77.7 3.10 0.071 1.42 0.4771 6 82.1 7.58 0.071 2.08 0.7160 32 98.8 5.60 0.143 3.27 1.7160 36 93.3 4.74 0.097 4.16 1.7160 ... I cannot find any documentation for the exact format of the data matrix for this function (http://www.inside-r.org/packages/cran/soil.spec/docs/ken.sto does not have this information).
