In leeper/UNF: Tools for Creating Universal Numeric Fingerprints for Data

UNF 2.0.5

• Exported new function unf_equal() to better comply with R CMD check.
• Converted package to use roxygen documentation.
• Improved implementation of raw vector handling.
• Expanded test suite to cover raw, AsIs, and time-series vectors. (#17)

UNF 2.0.4

• Added a unfmatch element to the return value of %unf%.
• Expanded test suite to cover %unf%. (#17)

UNF UNF 2.0.3

• Expanded test suite to cover as.unfvector(). (#2)

UNF 2.0.2

• Allow %unf% to be used to compare against a character string containing a UNF signature (#16, h/t Dominik Vogel)
• Converted unf() to an S3 generic, with matrix, list, and data.frame methods.
• Exposed new function as.unfvector(), which coerces data types to UNF character vector specifications. (#15)
• Added base package imports to NAMESPACE. (#14)

UNF 2.0.1

• Fix error in datetime tests due to use %F (not supported on Windows for R3.0.3). (#13)

UNF 2.0

• Support UNF version 6. (#2)
• Entirely rewrite codebase in R using digest.

UNF 1.02

• Standardizes representation of non-finite numbers as : +inf, -inf, +nan
• Allows for separate specification of rounding levels for character and numeric vectors
• Composite unfs are sorted by unf value which disambiguates ordering
• Discovered that sprintf() internal rounding behavior is inconsistent. Now use explicit rounding using IEE 753 "round to nearest".
• UNF Version 4, replaces MD5 with SHA256 algorithm
• check with codetools()
• remove -static (request from Brian Ripley)

UNF 1.04

• Set locale for sort order
• Add vignette
• Move citation

UNF 1.05

• fix bug in as.unf

UNF 1.06

• workaround for lack of posix locale under windows

UNF 1.07

• Protocol v. 4.1, perf, as.unf bug

UNF 1.08

• code comments

UNF 1.09

• fix prototyping bug, add other languages

UNF 1.10

• fix suppression of digits for default under v3

UNF 1.11

• fix non C99 #includes

UNF 1.13

• inital changes for Splus compatability

UNF 1.14

• Namespace imports, other SPLUS changes

UNF 1.15

• Splus for linux debug
