Utility to benchmark expression in R — benchmarkito • ergmito

This is just an internal utility included in the package which is not designed to be accurate. If you need accurate benchmarks, you should take a look at the microbenchmark and bench R packages.

benchmarkito(..., times = 100, rand_ord = TRUE)

Arguments

...	List of expressions to benchmark.
times	Integer scalar. Number of replicates.
rand_ord	Logical. When `TRUE`, the expressions are executed in a random order.

Value

A data frame of class ergmito_benchmark with times rows and the following columns:

id Integer. Id of the expression.
expr Factor. Expression executed.
user.self, sys.self, elapsed, sys.child time in seconds (see proc.time()).

Includes the following attributes: ncalls, call, label, and expr.

Details

The print method prints a summary including quantiles, relative elapsed times, and the order (fastest to slowest).

Examples

bm <- benchmarkito(
  exp(1:100000),
  sqrt(1:100000),
  times = 20
)

plot(bm)
print(bm)
