Leave-one-out cross-validation

[santeldm]

I am using the R interface to optunity. Does it support LOO cross-validation? I would expect to be able to call cv.setup() with num_folds = (number of rows in data matrix), but whenever I set num_folds to more than 50% of the number of rows, I get the following error:

Error in newdata[, object$scaled, drop = FALSE] : (subscript) logical subscript too long
