Dear useRs,

a new and completely re-worked version of the "simecol" package

   SIMulatiion of ECOLogical (and other) dynamic systems

is now available on CRAN. Compared to the S3 based 0.2-x versions an improved object model using S4 classes was employed. Please ask me for assistance in case of incompatibility.

Comments are welcome, Thomas Petzoldt


Abstract:


The simecol package is intended to give users (scientists and students) and interactive environment to implement, distribute, simulate and document ecological and other dynamic models without the need to write long simulation programs. An object oriented approach based on the S4 class system is proposed, which should provide a consistent but still flexible and extensible way to implement dynamic models.

Models of different type are provided as data and in source code (see directory "examples") which are intended as a starting point to write and distribute your own simObj models.

The package is supplemented with several utility functions (e.g. seedfill or neighbours), which can be used independently from simObj objects.

More Info:


? simecol-package: general description of the package ? parms: functions to get or set model parameters etc.

Examples:


file.show(system.file("examples/lv.R", package = "simecol"))
file.show(system.file("examples/conway.R", package = "simecol"))
file.show(system.file("examples/upca.R", package = "simecol"))
