Note that it's pretty usual (it even presents it this in the help) to pass your state variable in the form y0 = list(N=2), p=list(r=0.5, K=1000) then you'd wrap the body of clogistic() with(c(y0, p), {...}) and can use your states and parameters directly, i.e. N, r, K, instead of the less obvious y[1], p[1], p[2]. clogistic
your videos are very helpful. thank you very very much. can you make a playlist on CROSS VALIDATION, LDA/QDA, PCA,SVM i would really appreciate it!!!! thanks in advance
How can I control my model to not produce any negative values? (or any number below 1e-6 to consider as zero). I could not find any option not in ode nor Isoda function. Thank you so much for your answer.

Dear Tom, Could you gives us an example on how to solve 1st order partial differential equations?
very helpful. thumbs up
Can you please explain some line of codes if we have different variables data for period of time in excel sheet. Thank you
Hi, nice video. I got a question. What should I do in case I would have a data base and have to do a simulation for any row of the data? Thanks!

Dear sir, can you please explain, Kuznets Curve in R. Please sir.
How can I control my model to not produce any negative values? (or any number below 1e-6 to consider as zero). I could not find any option not in ode nor Isoda function.
Thank you so much for your answer.
Have you found an answer? If you still need it I can share my code
