errors 0.4.2

• Add support for PDG rounding rules (@davidchall #59 addressing #45).
• Improve formatting of null values (#48).

errors 0.4.1

• Switch from size (deprecated in ggplot2 v3.4.0) to linewidth aesthetic in geom_errors() (#55).
• Implement methods for dealing with missing values in errors objects, and fix na.rm behavior for summary methods (#56).
• Performance improvements for data.frame methods.

errors 0.4.0

• Add new geom_errors() function to automatically add errorbars to ggplot2 plots for variables of class errors (#52).
• Some fixes in plot.errors(), improved units compatibility.
• Implement errors methods for duplicated(), anyDuplicated() and unique().
• Fix operators %/% and %% (#54).

errors 0.3.6

• Fix check tolerance when correlations are approx. 1 (#42).

errors 0.3.5

• Internal performance improvements (#39).

errors 0.3.4

• vctrs methods are now implemented for compatibility with dplyr 1.0 (#38).
• Implement prettier str() print (#36).
• Implement drop method for data frames.

errors 0.3.3

• Fix min(), max() and range() (#35).
• Rewrite plot() to fix issues with limits and labels (#35).

errors 0.3.2

• Add CITATION for the R Journal paper.
• Add the paper as a vignette.

errors 0.3.1

New features

• Add a new dataset from the Annex H of the Guide to the Expression of Uncertainty in Measurement (GUM) and associated example (f6e5461, see ?GUM.H.3).
• Provide methods for logical values to automatically reinterpret NA as NA_real_ (#30).
• Add delayed S3 registration mechanism for R >= 3.6.0 (955e7ad).

Minor changes and fixes

• Move GUM examples to ?`errors-package` and provide new examples for ?correl (aed40eb).
• Simplify object ID handling (#27).
• Fix formatting in presence of missing values (as part of #30).
• Fix Summary.errors() to deal with named arguments (dd4607b).

errors 0.3.0

New features

• Implement as.list() for errors objects (7aff546).
• Implement support for correlations between variables (#26). The correl() and covar() methods set and retrieve pairwise correlations or covariances, respectively, between errors objects, thereby completing the full first-order Taylor series method of propagation of uncertainty.
• Add a new dataset from the Annex H of the Guide to the Expression of Uncertainty in Measurement (GUM) (as part of #26; see ?GUM.H.2 and examples under ?correl).
• Implement all.equal() for errors objects (as part of #26), which returns TRUE for different (different internal identifier) objects with the same quantity values and uncertainty. To compare whether two variables are exactly the same object, identical() should be used instead.

Minor changes and fixes:

• Fix encoding issues for the plus-minus symbol (#24).
• Fix pillar representation (14df89b).
• Fix coercion issues (0e04519).
• Improve documentation (as part of #26).

errors 0.2.1

New features

• New drop_errors() method drops errors class and attributes. Equivalent to setting a NULL error (#23).
• Implement pillar_shaft() for tidy tibble printing and improve type_sum() (700f1aa).

Minor changes and fixes:

• Show Ops() warnings once (#22).
• Refactor print() method (2c252d9).
• Drop support for matrix multiplication: no warning is issued anymore (090e953).
• Fix cbind()/rbind() column/row name parsing for named arguments (b8ea6b5).
• Improve plus-minus separator (8b3d231).
• Fix formatting to take into account the scipen option (9299551).

errors 0.2.0

Minor changes and fixes:

• Show a warning and drop errors in boolean operators instead of failing (#17).
• min(), max(), range() return numeric, including the error: value minus error, value plus error and (min, max) respectively (#18).
• Use structure() instead of set_errors() internally (#20).
• Improved support for matrices and data frames with the implementation of rbind(), cbind(), as.data.frame() for errors objects (#21).
• Improved documentation and testing (#19).

errors 0.1.0

Minor changes and fixes:

• Improved support for arrays and matrices (#4).
• Inf, NaN and NA values default to Inf, NaN and NA errors respectively (#10).
• Drop errors with a warning in matrix multiplication (#11).
• Fix errors defined as integers (#12).
• Do not allow boolean operators on errors objects (#13).
• Give a default value to set_errors() (#14).
• Tidy tibble printing (#15).
• Correct plot limits according to error bars (#16).

errors 0.0.2

Minor changes and fixes:

• Fix exponentiation with negative base (#2).
• Fix formatting when the value equals zero (#3).
• Fix formatting when the error equals zero (#5).
• Take digits into account for errors in vector display (#7).
• Fix deletion of trailing zeroes in plus-minus notation (#8).
