my_knn_cv: K-Nearest Neighbors Cross Validation

In Jenniferdny/mySTAT302package: Project 3 Package

Description

Function doing Cross Validation test for the KNN model.

Usage

my_knn_cv(train, trueValues, n, f)

Arguments

train	DataFrame, input including the training variable.
trueValues	Vector, input the true class value of training data.
n,	Numeric input, is the number of neighbors.
f	Numeric input folds.

Value

a list includes class, a vector of the predicted class y-hat for all observations, cv_err, a numeric of the cross-validation misclassification error.

Examples

penguins_data <- na.omit(my_penguins)
train <- penguins_data[, 3:6]
trueValues <- penguins_data$species
my_knn_cv(train, trueValues, 5, 5)
