R has packages deSolve for solving differential equations and FME for parameter fitting. The specific example here is taken from the computational appendix (A.6) of the book Chemical Reactor Analysis and Design Fundamentals by Rawlings and Ekerdt. In fact, all examples in this book are available in Octave and MATLAB.

Solving ODEs in R Since these equations are nonlinear, it’s not surprising that one can’t solve them analytically. However, we can compute the trajectories of a continuous-time model such as this one by integrating the equations numerically.

R has three packages that are useful for solving partial differential equations. The R package ReacTran offers grid generation routines and the discretization of the advective-diffusive transport In this paper we present the R package deSolve to solve initial value problems (IVP) written as ordinary differential equations (ODE), differential algebraic equations (DAE) of index 0 or 1 and partial differential equations (PDE), the latter solved using the method of lines approach. The differential equations can be represented in R code or as About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators One of the fields where considerable progress has been made is the solution of differential equations. Here we first give an overview of the types of differential equations that R can solve, and then demonstrate how to use R for solving a 2‐Dimensional partial differential equation. R has three packages that are useful for solving partial differential equations.

diffeqr diffeqr is a package for solving differential equations in R. It utilizes DifferentialEquations.jl for its core routines to give high performance solving of ordinary differential equations (ODEs), stochastic differential equations (SDEs), delay differential equations (DDEs), and differential-algebraic equations (DAEs) directly in R. Im trying to solve differential equations in R but I cant a way to move it into the language. Im trying to solve these y'=2x and y'=2y.
