All.equal.nanotime

Test if Two Objects are (Nearly) Equal

Description

Compare target and current testing ‘near equality’. If they are different, comparison is still made to some extent, and a report of the differences is returned. Do not use all.equal directly in if expressions—either use isTRUE(all.equal(....)) or identical if appropriate.

Usage

## S3 method for class 'nanotime'
all.equal(
  target,
  current,
  tolerance = sqrt(.Machine$double.eps),
  scale = NULL,
  countEQ = FALSE,
  formatFUN = function(err, what) format(err),
  ...,
  check.attributes = TRUE
)

## S4 method for signature 'nanotime'
all.equal(
  target,
  current,
  tolerance = sqrt(.Machine$double.eps),
  scale = NULL,
  countEQ = FALSE,
  formatFUN = function(err, what) format(err),
  ...,
  check.attributes = TRUE
)

Arguments

Argument Description
target, current nanotime arguments to be compared
tolerance numeric >= 0. Differences smaller than tolerance are not reported. The default value is close to 1.5e-8.
scale NULL or numeric > 0, typically of length 1 or length(target). See ‘Details’.
countEQ logical indicating if the target == current cases should be counted when computing the mean (absolute or relative) differences. The default, FALSE may seem misleading in cases where target and current only differ in a few places; see the extensive example.
formatFUN a function of two arguments, err, the relative, absolute or scaled error, and what, a character string indicating the _kind_ of error; maybe used, e.g., to format relative and absolute errors differently.
... further arguments for different methods
check.attributes logical indicating if the attributes of target and current (other than the names) should be compared.
