map_precisely: Calculate with precisely functions across values

In precisely: Estimate Sample Size Based on Precision Rather than Power

Description

map_precisely() is a wrapper around tidyr::crossing() and purrr::pmap_dfr() to give a set of values to any of the calculation functions in precisely. All possible combinations of the values are passed to the function, returning a tibble where each row is the result for each combination.

Usage

map_precisely(.f, ...)

Arguments

.f	a function in precisely
...	arguments passed to .f. All possible combinations of argument values are given to the function.

Value

a tibble

Examples

map_precisely(
  n_risk_difference,
  precision = seq(from = .02, to = .20, by = .005),
  exposed = c(.2, .4),
  unexposed = c(.1, .3),
  group_ratio = 1
)
