# version 0.7-1 * allow longer units grouping; #270 addressing #269 @bart1 * fix regression in `set_units` method for `mixed_units` to ensure that ordering is preserved; #272 addressing #271 # version 0.7-0 * add `load_units_xml` to enable database reloading as well as loading user-provided unit systems; #254 addressing #243, #244 * add `install_unit` and `remove_unit` for adding/removing custom user-defined symbols or names, with optional mapping to existing units; `install_symbolic_unit`, `remove_symbolic_unit`, `install_conversion_constant`, `install_conversion_offset` are deprecated; #261 addressing #89 * add `keep_units`, a helper to apply functions that do not preserve units; #255 addressing #252 * fix `as_units("")`, which is now equivalent to `unitless`; #199 * fix plot axes for `plot.formula` and `plot.data.frame`; #213 * fix arithmetic for powers above 1 and below -1; #264 * improve arithmetic of logarithms; #249 * export `ud_are_convertible`; #263 addressing #258 @cregouby * remove deprecations: `as.units`, `as_cf`, `make_unit`, `parse_unit`; #259 * remove deprecated pre-computed `ud_units` database; #259 # version 0.6-7 * port `isFALSE` to fix regression in old R versions; #230 addressing #229 * fix replacement operation for `units` objects; #233 addressing #232 * fix compatibility with dplyr 1.0; #247 addressing #239 # version 0.6-6 * prettier `str` print for units and mixed units; #228 addressing #227 * add compatibility with upcoming tibble v3.0.0; #225

Support for measurement units in R vectors, matrices and arrays: automatic propagation, conversion, derivation and simplification of units; raising errors in case of unit incompatibility. Compatible with the POSIXct, Date and difftime classes. Uses the UNIDATA udunits library and unit database for unit compatibility checking and conversion.
