Translate between deSolve and DifferentialEquations.jl solver names

Source: R/sim_methods.R
sim_methods.Rd

Translate between deSolve and DifferentialEquations.jl solver names, or validate that a given solver name is recognized in either language. This is used internally to allow users to specify familiar R solvers when using Julia for simulation, and to provide warnings when an exact equivalent is not available.

Usage

sim_methods(method, from = NULL, to = NULL)

Arguments

method

Solver name to validate or translate.

from

Source solver family, either "R" or "Julia".

to

Target solver family when translating, either "R" or "Julia".

Value

A character scalar (validated or translated solver name), a character vector of solver names when method is omitted, or a named list of solver names for both languages when called with no arguments.
