formula, x, y, data |
formula and data arguments of function to be tuned. |
predict.func |
predicting function. |
na.action |
function handling missingness. |
minsplit, minbucket, cp, maxcompete,
maxsurrogate, usesurrogate, xval,
surrogatestyle, maxdepth |
rpart parameters. |
degree, gamma, coef0, cost, nu, class.weights |
svm
parameters. |
k, l |
knn parameters. |
mtry, nodesize, ntree |
randomForest parameters. |
size, decay, trace |
parameters passed to
nnet. |
tunecontrol |
object of class "tune.control" containing
tuning parameters. |
... |
Further parameters passed to tune. |
For examples, see the help page of tune().
tune.foo() returns a tuning object including the best parameter set obtained
by optimizing over the specified parameter vectors. best.foo()
directly returns the best model, i.e. the fit of a new model using the
optimal parameters found by tune.foo.
