get_complex: Access internal simulation variables

In Avi-Kenny/SimEngine: A Modular Framework for Statistical Simulations in R

Access internal simulation variables

Description

Extract complex simulation data from a simulation object

Usage

get_complex(sim, sim_uid)

Arguments

sim	A simulation object of class sim_obj, usually created by new_sim
sim_uid	The unique identifier of a single simulation replicate. This corresponds to the sim_uid column in sim$results.

Value

The value of the complex simulation result data corresponding to the supplied sim_uid

Examples

sim <- new_sim()
sim %<>% set_levels(n=c(10, 100, 1000))
create_data <- function(n) {
  x <- runif(n)
  y <- 3 + 2*x + rnorm(n)
  return(data.frame("x"=x, "y"=y))
}
sim %<>% set_config(num_sim=2)
sim %<>% set_script(function() {
  dat <- create_data(L$n)
  model <- lm(y~x, data=dat)
  return(list(
    "beta0_hat" = model$coefficients[[1]],
    "beta1_hat" = model$coefficients[[2]],
    ".complex" = list(
      "model" = model,
      "cov_mtx" = vcov(model)
    )
  ))
})
sim %<>% run()
c5 <- get_complex(sim, sim_uid=5)
print(summary(c5$model))
print(c5$cov_mtx)
