Analysis Tools for the 'JAMES' Framework

Analyze and visualize results of studies performed with the analysis tools in 'JAMES', a modern object-oriented Java framework for discrete optimization using local search metaheuristics (see http://www.jamesframework.org).


Build Status

The JAMES analysis R package is part of the JAMES framework. This R package is used to analyze and visualize results obtained using the analysis tools from the extensions module.

Install

The package is available on CRAN. It can be installed with:

install.packages("james.analysis")

To load the package after installation:

library(james.analysis)

Documentation

Use data <- readJAMES("path/to/file") the load a JSON file in R that was created using the analysis tools from the JAMES extensions module (in Java). An object of class james is returned. Run summary(data) to summarize the results, or mergeJAMES and reduceJAMES to manipulate them.

To extract data, the following functions are provided:

  • getProblems
  • getSearches
  • getSearchRuns
  • getNumSearchRuns
  • getBestSolutions
  • getBestSolutionValues
  • getConvergenceTimes

To visualize the results, use:

  • plotConvergence
  • boxplot

Detailed documentation is provided for each function and can be accessed by typing ?function, as usual. To view the help file for the box plots, type ?boxplot.james (this is an implementation of the S3 method boxplot from the standard graphics package for class james).

Examples

Some examples are included in the help files of the available functions. More extensive examples of how to analyze the results will soon be provided at the website.
