compareCoerce {compare}

Compare Two Objects of Different Class

Description

Compare two objects for equality, coercing the comparison object to the same class as the model object if necessary beforehand.

Usage

compareCoerce(model, comparison, transform = character(),
              equal = TRUE, ...)

## S3 method for class 'data.frame'
compareCoerce(model, comparison,
              transform=character(),
              equal=TRUE,
              ignoreColOrder=FALSE,
              ignoreNameCase=FALSE,
              ...) 

Arguments

model

The “correct” object.

comparison

The object to be compared with the model.

transform

A character vector containing any transformations that have been performed on the objects prior to this comparison.

equal

Whether to test for equality if the test for identity fails.

ignoreColOrder

For data frames, whether to reorder columns by name first.

ignoreNameCase

For data frames and lists, whether to ignore the case of names when reordering components by name.

...

Arguments passed to compareEqual().

Details

This function is generic, with methods for logical, integer, numeric, and character vectors, factors, arrays, matrices, tables, data frames, and lists.

The integer and numeric methods use the appropriate special-case coercion for factors.

Value

An object of class "comparison". Use isTRUE() to determine whether the comparison has succeeded.
