Create a new (empty) medley object

1 2	create.medley(x, y, label = "", errfunc = rmse, base.model = NULL, folds = 8)

`x`	matrix of predictors
`y`	vector of response values
`label`	a unique label for this medley (used in status messages)
`errfunc`	an error metric for this medley
`base.model`	a function to use as a baseline model
`folds`	the default number of cross-validation folds to use

require(e1071);
data(swiss);
x <- swiss[,1:5];
y <- swiss[,6];
train <- sample(nrow(swiss), 30);
m <- create.medley(x[train,], y[train]);
for (gamma in c(1e-3, 2e-3, 5e-3, 1e-2, 2e-2, 5e-2, 1e-1, 2e-1, 5e-1, 1)) {
  m <- add.medley(m, svm, list(gamma=gamma));
}
p <- predict(m, x[-train,]);
rmse(p, y[-train]);
