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.
The package comes with ABSOLUTELY NO WARRANTY. This is
free software with all R code available under a copyleft
left. However, some of the underlying Java code its use
restricted to NON-COMMERCIAL use. Read the file "LICENSE" of
the package for a long story about the unresolved licensing
issue of "RLadyBug", which currently prevents it to
re-appear on CRAN.
The RLadyBug package used to be available
(0.6-1). In Apr 2012 it was removed from CRAN due to
inactivity and once I've tried to upload again, it's not
allowed again due to a Catch 22 licensing issue. So meanwhile,
sources and binaries of the current version 0.7-1 can be found
[16/02/2013] Version 0.7-1 is now available from this
webpage. It contains a fix of the onLoad issues, which
caused it to be removed from CRAN. Also note that the
twinSIR functionality is not part of the package anymore. It
has been moved to the R package surveillance.
[Apr 2012] Package removed from CRAN.
[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.
Addon: The functionality has been moved to the R package
surveillance as function "twinSIR".
[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 >=
