The R-Package "RLadyBug"

• Analysis of small scale infectious diseases possibly with a spatial grid component using stochastic Susceptible-Exposed-Infectious-Recovered models (SEIR). The R package wraps functionality of a Java program, thus a java virtual machine has to be installed on your computer.

• Frequently Asked Questions (FAQ)

• [10/10/2009] Version 0.6-0 is now available from CRAN. The package now contains an implementation of the two-component SIR model described in Höhle (2009), Additive-Multiplicative Regression Models for Spatio-Temporal Epidemics, which is accepted for publication in Biometrical Journal. A preprint of the work can be found here.
  
• [02/02/2009] Version 0.5-0 available from CRAN. Experimental code for additive-multiplicative model fitting.
  
• [16/01/2008] Version 0.4-3 available from CRAN. Contains bug fixes and the handling of unknown recovery times.
• [24/09/2007] Version 0.4-2 is now available from CRAN. The update mainly consists in making the package compatible with the new rJava version and converting .RData objects to >= 2.4.0 format
  
• [09/01/2007] The package use is described in the paper RLadyBug—An R package for stochastic epidemic models, Computational Statistics and Data Analysis, 52(2), pp. 680-686. 
• [03/08/2006] RLadyBug v0.4 is now available. The Java program is envoked using the rJava interface, plot methods have been made more concordant with R and data is now loadable with data().
• [01/03/2006] RLadyBug v0.1 is now available. For a quick demo try demo("article-csda") after installing the package.
