Extract information from a compiled model or a simulated tree sequence

This function extract a slendr model parameters used to compile a given model object or simulate a tree sequence

Usage

extract_parameters(data)

Arguments

data

Either an object of the class slendr_ts or slendr_model

Value

A list of data frames containing parameters of the model used when compiling a model object

Examples

check_dependencies(python = TRUE, quit = TRUE) # dependencies must be present

init_env()
#> The interface to all required Python modules has been activated.

# load an example model and simulate a tree sequence from it
model <- read_model(path = system.file("extdata/models/introgression", package = "slendr"))
ts <- msprime(model, sequence_length = 1e5, recombination_rate = 0)
