evals {simulator} | R Documentation |
Get one or more evals from a simulation
Description
Returns either the Evals object itself or a reference to it.
Usage
evals(sim, ..., subset = NULL, index, methods, reference = FALSE)
Arguments
sim |
a simulation object |
... |
logical conditions to specify a subset of models. Conditions can only involve params of model that have length 1 and are of class numeric or character. |
subset |
a vector of integers indexing the models or a vector of model
names. To select models based on parameter values, use |
index |
a vector of positive integers specifying which draws' objects are desired. If missing, then all draws' evals are returned. |
methods |
character vector of method names of interest. If missing, then all methods' evals are returned |
reference |
whether to return the ModelRef or the Model object itself |

Examples
## Not run:
# suppose previously we had run the following:
sim <- new_simulation(name = "normal-example",
label = "Normal Mean Estimation",
dir = tempdir()) %>%
generate_model(make_my_example_model, n = 20) %>%
simulate_from_model(nsim = 50, index = 1:3) %>%
run_method(my_example_method) %>%
evaluate(my_example_loss)
# then we could get the metric evaluated on the method's output:
e <- evals(sim)
# we can export it as a data.frame
as.data.frame(e)
# or we can get at a particular draw-method-metric triplet
e@evals$`my-method`$r1.1$myloss
