When I used the package "ada" to realize a boosting algorithm, there occures a
bug.
I use the function "ada" to produce a ada object from the training data. After
that, I use the function "predict.ada" to predict the output for just ONE input,
but the result is a vector containing 50 numbers.
However, if I use the "predict.ada" to predict the outpt for a data.frame which
contains several input, the function will calculate the correct result.
