Hi Mohammad

KNN is already developed in R, use following

#Install class package

install.packages('class')

# Load class package

library(class)

data(iris)

train

You may find it useful to explore the general example of kNN algorithm in R.

Just check for the function “knn” in R. If it isn’t already installed, you first have to install the package; I think the name package is still “knn”.

You may also want to use the package “caret”. It contains different functions (as knn) for modelling complex regression and classification problems.

Use install.packages('class')

use the following libreraries (class, dployr)

the packages RANN and nabor have two functions nn2(RANN) y knn (nabor)
