bench_compare

Evaluate, compare, benchmark operations of a set of srcs.

Description

These functions are deprecated because we now believe that you're better of performing the comparisons directly, yourself, in order to generate more informative test failures.

Usage

bench_tbls(tbls, op, ..., times = 10)

compare_tbls(tbls, op, ref = NULL, compare = equal_data_frame, ...)

compare_tbls2(tbls_x, tbls_y, op, ref = NULL, compare = equal_data_frame, ...)

eval_tbls(tbls, op)

eval_tbls2(tbls_x, tbls_y, op)

Arguments

`tbls, tbls_x, tbls_y`	A list of `tbl()`s.
`op`	A function with a single argument, called often with each element of `tbls`.
`...`	For `compare_tbls()`: additional parameters passed on the `compare()` function For `bench_tbls()`: additional benchmarks to run.
`times`	For benchmarking, the number of times each operation is repeated.
`ref`	For checking, a data frame to test results against. If not supplied, defaults to the results from the first `src`.
`compare`	A function used to compare the results. Defaults to `equal_data_frame` which ignores the order of rows and columns.

Value

eval_tbls(): a list of data frames.

compare_tbls(): an invisible TRUE on success, otherwise an error is thrown.

bench_tbls(): an object of class microbenchmark::microbenchmark()
