data
the dataframe containing the independent variables and the response
iterations
The number of training rounds for boosting.
verbose
should the current training round be printed to the console?
k <- kyphosis
k$Kyphosis <- factor(ifelse(k$Kyphosis == "present", 1L, -1L))
fit <- fitBoosted(Kyphosis ~ Age + Number + Start, data = k, iterations = 10)
