units_options {units}R Documentation

set one or more units global options

Description

set units global options, mostly related how units are printed and plotted

Usage

units_options(..., sep, group, negative_power, parse, set_units_mode,
  auto_convert_names_to_symbols, simplify)

Arguments

...

ignored

sep

character length two; default c("~", "~"); space separator between variable and units, and space separator between two different units

group

character length two; start and end group, may be two empty strings, a parenthesis pair, or square brackets; default: square brackets.

negative_power

logical, default FALSE; should denominators have negative power, or follow a division symbol?

parse

logical, default TRUE; should the units be made into an expression (so we get subscripts)? Setting to FALSE may be useful if parse fails, e.g. if the unit contains symbols that assume a particular encoding

set_units_mode

character; either "symbols" or "standard"; see set_units; default is "symbols"

auto_convert_names_to_symbols

logical, default TRUE: should names, such as degree_C be converted to their usual symbol?

simplify

logical, default NA; simplify units in expressions?

Details

The default NA value for simplify means units are not simplified in set_units or as_units, but are simplified in arithmetical expressions.

Examples

units_options(sep = c("~~~", "~"), group = c("", "")) # more space, parenthesis
## set defaults:
units_options(sep = c("~", "~"), group = c("[", "]"), negative_power = FALSE, parse = TRUE)
