In r-quantities/quantities: Quantity Calculus for R Vectors

quantities devel

• Performance improvements for data.frame methods.

quantities 0.2.1

• Fix a couple of tests (r-quantities/units#324).

quantities 0.2.0

• Add compatibility between errors::geom_errors (r-quantities/errors#52) and units::scale_[x|y]_units (r-quantities/units#294) (#13).
• Fix warning in as.list.quantities.
• Add plotting examples to introductory vignette.
• Add support for errors with units (#14). For objects of class quantities or units, the errors() method now returns a units object that matches the units of x. Methods errors<-() and set_errors() assume that the provided uncertainty (value) has the same units as x (for backwards compatibility). However, it is a best practice to provide a value with explicit units. In this way, uncertainty can be provided in different (but compatible) units, and it will be automatically converted to the units of x (see help("errors", "quantities")).
• Add support for correlations and covariances with units for objects of class quantities (as part of #14).
• Remove some superfluous .quantities methods (as part of #14).
• Implement methods for duplicated, anyDuplicated and unique (#12).

quantities 0.1.6

• Fix compatibility with units 0.7-0.

quantities 0.1.5

• Fix compatibility with dplyr 1.0.0 (#8), coordinated with units and errors.
• Fix uncertainty propagation for mixed scaling+offset unit conversion, such as Celsius to Fahrenheit (#9).

quantities 0.1.4

• Add compatibility with upcoming tibble v3.0.0 (r-quantities/units#225).
• Implement prettier str print (#5).
• Implement drop method for data frames.
• Fix introduction vignette for dplyr >= 1.0.0.

quantities 0.1.3

• Add CITATION to units and errors in the R Journal.
• Fix unit simplification in arithmetical operations (#3).

quantities 0.1.2

• Add delayed S3 registration mechanism for R >= 3.6.0 (a9bb97e).

quantities 0.1.1

• Initial CRAN release.
