Solving a multinomial gompertz partial differential equation in r
3 messages · Brandon Breitling, Suzen, Mehmet, Thomas Petzoldt
Hi Brandon, You can try ReacTran package: cran.r-project.org/web/packages/ReacTran/vignettes/PDE.pdf Best, -m

I haven't used r in quite a while but would like to get back into it. I
have a problem that I would like to solve with r. I have some multinomial
data that looks to follow an asymmetric sigmoidal growth pattern. Solving
a multinomial gompertz partial differential equation in r is what I?m after.
Would anyone be able to provide me the code and packages to do something
like this?

ReacTran is for managing the tr5ansport in reactive transport models, is relies on package deSolve that contains the ODE/PDE solvers, so I would recommend to start with this first. Papers, slides and tutorials with full source code can be found at: http://desolve.r-forge.r-project.org ... and an overview about packages dealing with differential equations can be found in the Taskview: http://cran.r-project.org/web/views/DifferentialEquations.html Hope it helps Thomas Petzoldt
