In brodieG/alike: Compare Object Structure

alike 1.2.0

Deprecation
Fixes related to function comparison (#38, #37) and other misc (#36)

alike 1.1.0

Improvements to error message so that user can just copy paste relevant part of error message in prompt and see what the problem object is (fix issues #26, #32, #35)
- Use substituted current expression
- Use accessor functions to problem item (e.g. names(abc$b[[1]]))

alike 1.0.0

API Breaking Changes:

alike no longer accepts any parameters outside of target and current; if you wish to change the previously existing settings use .alike and alike_settings instead.

Behavior Changes:

We now only check small numeric vectors for integerness to avoid scanning through large numeric vectors to confirm they are integer like (you can re-enable this using the max.fuzzy.int.len parameter).
Added support for additional recursive objects: environments, pairlists, and expressions are now recursed through, with alike applied recursively to each elemment therein; this mirrors the previous treatment for lists (the VECSXP type)
Levels are compared like names (#23)
Improved comparison of language objects (calls, symbols, formulas, and functions); see docs for explanations of what makes language objects alike (#10, #11, #14, #16)
Attributes are now recursively compared with alike as well instead of identical
Added abstract functions to assist in the creation of template objects (#9)
ts class objects now have specialized comparison
Error messages generally tweaked

Other:

Documentation updates
Vignette overhaul

Internal Changes:

C level optimizations (#7, #13, but #13 not complete)
Several small unreported bugs

alike 0.2.5

Doc updates
removed C library files to allow installs on platforms with different compilers

alike 0.2.4

NULLs are only wildcard when nested inside other objects

alike 0.2.3

Clearer error messages focus on highest level differences first (e.g. class)
names/row.names may now be shorter in target than current
major internal re-structuring; should be transparent to user

NOTE: alike will likely cease to exist as a stand alone package and become part of validate at some point in the future. If this happens the interface will be unchanged, but the functions will be in a different package.

alike 0.2.2

Internal changes to support validate

alike 0.2.1

Now unloading dynamic libraries on package unload (Fixes #1), though some questions as to whether this introduces other issues when loading/unloading same package (happened once, can't reproduce).
