all.equal: Comparison of hyperSpec objects

Description

Comparison Operators: <,>, <=,>=, ==, and != The comparison operators >, <, >=, <=< code="">, ==, and != for hyperSpec objects.

Usage

## S3 method for class 'hyperSpec,hyperSpec':
all.equal(target,
    current, ..., check.attributes = FALSE,
    check.names = FALSE, check.column.order = FALSE,
    check.label = FALSE, check.log = FALSE)
  ## S3 method for class 'hyperSpec,hyperSpec':
Compare(e1, e2)
  ## S3 method for class 'hyperSpec,numeric':
Compare(e1, e2)
  ## S3 method for class 'hyperSpec,matrix':
Compare(e1, e2)
  ## S3 method for class 'numeric,hyperSpec':
Compare(e1, e2)
  ## S3 method for class 'matrix,hyperSpec':
Compare(e1, e2)

Arguments

target,current

two hyperSpec objects that are tested for equality

...

handed to all.equal when testing the slots of the hyperSpec objects

check.column.order

If two objects have the same data, but the order of the columns (determined by the names) differs, should they be regarded as different?

check.label

Should the slot label be checked? If the labels differ only in the order of their entries, they are conidered equal.

check.log

Should the slot label be checked?

check.attributes,check.names

see all.equal

e1,e2

Either two hyperSpec objects or one hyperSpec object and matrix of same size as hyperSpec[[]] or a scalar (numeric of length 1).

As hyperSpec objects must have numeric spectra matrices, the resu

Value

• all.equal returns either TRUE, or a character vector describing the differences. In conditions, the result must therefore be tested with isTRUE.

  a logical matrix for the comparison operators.

Details

all.equal checks the equality of two hyperSpec objects.

The comparison operators >, <, >=, <=< code="">, ==, and != work on the spectra matrix of the hyperSpec object. They have their usual meaning (see Comparison). The operators work also with one hyperSpec object and a numeric (scalar) object or a matrices of the same size as the spectra matrix of the hyperSpec object.

With numeric vectors sweep might be more appropriate.

If you want to calculate on the data.frame hyperSpec@data, you have to do this directly on hyperSpec@data.
