Description Usage Arguments Details Value Examples

View source: R/ipredknn.R

Description

$k$-nearest neighbour classification with an interface compatible to bagging and errorest.

Usage

1

Arguments

formula

a formula of the form lhs ~ rhs where lhs is the response variable and rhs a set of predictors.

data

optional data frame containing the variables in the model formula.

subset

optional vector specifying a subset of observations to be used.

na.action

function which indicates what should happen when the data contain NAs.

k

number of neighbours considered, defaults to 5.

...

additional parameters.

Details

This is a wrapper to knn in order to be able to use k-NN in bagging and errorest.

Value

An object of class ipredknn. See predict.ipredknn.
