addUrlToClassPath

a character representing the complete path to the directory or the JAR file
if the packageName parameter is null. Otherwise, it can just be the name of the JAR file.

urlString

a character representing the package.

packageName

This function makes it possible to add a directory or a JAR file
to the class path. If the packageName parameter is null then the urlString
parameter must be the complete path to the directory. Otherwise, it can be
the name of the JAR file and the function will find the path through the package
name. A non null packageName parameter is typically used in packages that rely
on J4R.

Makes it possible to create 'Java' objects and to execute 'Java' methods from the 'R' environment.
The 'Java' Virtual Machine is handled by a gateway server. Commands are sent to the server
through a socket connection from the 'R' environment. Calls to 'Java' methods allow for
vectors so that a particular method is iteratively run on each element of the vector. A
score algorithm also makes the calls to 'Java' methods less restrictive. The gateway server
relies on the runnable 'Java' library 'j4r.jar'. This library is licensed under the LGPL-3. Its
sources are included in this package.

addUrlToClassPath: Dynamically adds an url to the classpath.
