In raredd/rawr: rawr miscellaneous

Test if two or more objects are (nearly) equal

Description

A generalization of all.equal that allows more than two objects to be tested for near-equality.

Usage

all_equal2(
  ...,
  tolerance = .Machine$double.eps^0.5,
  scale = NULL,
  check.attributes = TRUE,
  use.names = TRUE,
  all.names = TRUE,
  check.names = TRUE
)

Arguments

...	any R objects
tolerance	numeric >= 0; differences smaller than tolerance are not reported (default value is close to 1.5e-8)
scale	numeric scalar > 0 (or NULL), see details in all.equal
check.attributes	logical indicating if the attributes should be compared
use.names	logical indicating if list comparison should report differing components by name (if matching) instead of integer index
all.names	logical passed to ls indicating if "hidden" objects should also be considered in the environments
check.names	logical indicating if the names(.) should be compared

Value

If all ... are nearly equal, TRUE otherwise returns a list with the objects that failed.

all_equal2(pi, 355/113, 22/7)

all_equal2(pi, 355/113, 22/7, tolerance = 0.01)
