glm.deploy (version 1.0.4)

glm2java: Java source code generator for rapid deployment of glm predictive models

Description

The glm2java() function is used to generate source code in Java language implementing a given glm predictive model. It implements the following two methods; the glm_xxx_response() and glm_xxx_link(), where xxx stands for the name of the target variable of the glm object. After invocation of the glm2java(), a .java file is generated containing the two predict methods which are declared as public static inside a java class called "glm_xxx_class".

Usage

glm2java(model, filename = NULL, path = NULL)

Arguments

model

A fitted object of class "glm".

filename

OPTIONAL The name of the output file, the default file name is "glm_xxx_class.java", where xxx is the target variable's name.

path

The directory path where files are going to be saved.

Examples

# NOT RUN {
 # Example with the iris dataset with a Logical target and numeric
 # variables, using the binomial family and the logit link function
 data(iris)
 iristest = iris
 iristest$Virginica = ifelse(iristest$Species == 'virginica', TRUE,FALSE)
 iristest$Species = NULL

 # Load Package
 library(glm.deploy)
 # For repeatable results
 set.seed(123)
 # Generate the fitted glm object
 m = glm(Virginica ~ ., family = binomial(logit), data=iristest)
 # Call the glm2java() function with default filename
 glm2java(m,, tempdir())
 # Call the glm2java() function with custom filename
 glm2java(m,'my_glm_virginica', tempdir())

 # The glm2java() function generates the file "glm_virginica_class.java".

# }
# NOT RUN {
