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? Regards,

Hello List, Can you recommend me if odeSolve can handle stiff delay differential equations with discontinuities? Or any other package? Best, -m

Hi, I am about to conduct an experiment of temperature dependent development of an insect. Here I would like to know is if I could be able to find the parameters of the models what I will use in data analysis with R program. I have found some other softwares that can be used for parameter estimation but liscence would be needed, not open source. So I prefer to use R langauge if it is reliable
