Plot density plots for numeric results and bar plots for non-numeric results of a Monte Carlo Simulation run by future_mc().

Usage

# S3 method for class 'mc'
plot(
  x,
  join = NULL,
  which_setup = NULL,
  parameter_comb = NULL,
  plot = TRUE,
  ...
)

Arguments

x

An object of class mc, for which holds simple_output = TRUE. See value of future_mc().

join

A character vector containing the nice_names for the different parameter combinations (returned by future_mc()), which should be plotted together. Default: Each parameter combination is plotted distinctly.

which_setup

A character vector containing the nice_names for the different parameter combinations (returned by future_mc()), which should be plotted. Default: All parameter combinations are plotted.

parameter_comb

Alternative to which_setup. A named list whose components are named after (some of) the parameters in param_list in future_mc() and each component is a vector containing the values for the parameters to filter by. Default: All parameter combinations are plotted.

plot

Boolean that specifies whether the plots should be printed while calling the function or not. Default: TRUE

...

ignored

Value

A list whose components are named after the outputs of fun and each component contains an object of class ggplot and gg which can be plotted and modified with the ggplot2::ggplot2 functions.

Details

Only one of the arguments join, which_setup, and paramter_comb can be specified at one time.

Examples


test_func <- function(param = 0.1, n = 100, x1 = 1, x2 = 2){

  data <- rnorm(n, mean = param) + x1 + x2
  stat <- mean(data)
  stat_2 <- var(data)

  if (x2 == 5){
    stop("x2 can't be 5!")
  }

  return(list(mean = stat, var = stat_2))
}

param_list <- list(param = seq(from = 0, to = 1, by = 0.5),
                   x1 = 1:2)

set.seed(101)
test_mc <- future_mc(
  fun = test_func,
  repetitions = 1000,
  param_list = param_list,
  n = 10,
  x2 = 2
)
#> Running single test-iteration for each parameter combination...
#> 
#>  Test-run successfull: No errors occurred!
#> Running whole simulation: Overall 6 parameter combinations are simulated ...
#> 
#>  Simulation was successfull!
#>  Running time: 00:00:00.836771
