ddalphaf.classify {ddalpha}

Classify using Functional DD-Classifier

Description

Classifies data using the functional DD-classifier.

Usage

ddalphaf.classify(ddalphaf, objectsf, subset, ...)

## S3 method for class 'ddalphaf'
predict(object, objectsf, subset, ...)

Arguments

ddalphaf, object

Functional DD-classifier (obtained by ddalphaf.train).

objectsf

list containing lists (functions) of two vectors of equal length, named "args" and "vals": arguments sorted in ascending order and corresponding them values respectively

subset

an optional vector specifying a subset of observations to be classified.

...

additional parameters, passed to the classifier, selected with parameter classifier.type in ddalphaf.train.

Value

List containing class labels.

Examples

## Not run: 
## load the Growth dataset
dataf = dataf.growth()

learn = c(head(dataf$dataf, 49), tail(dataf$dataf, 34))
labels= c(head(dataf$labels, 49), tail(dataf$labels, 34)) 
test  = tail(head(dataf$dataf, 59), 10)    # elements 50:59. 5 girls, 5 boys

c = ddalphaf.train (learn, labels, classifier.type = "ddalpha")

classified = ddalphaf.classify(c, test)

print(unlist(classified))
