Format according to SI conventions

Description

Format according to SI conventions

Usage

format_SI(
  x,
  digits = NULL,
  fixed = FALSE,
  engineering = FALSE,
  ...,
  verbose = getOption("verbose")
)

Arguments

x	(numeric)
digits	(numeric) passed to format_digits() under certain conditions (see Details)
fixed	(logical) see Details
engineering	(logical) see Details
...	reserved for future use / backwards-compatibility
verbose	(logical)

Details

If fixed is TRUE, the suffix will not be allowed to vary. The suffix corresponding to the largest value in abs(x) will be used.

If engineering is TRUE, the magnitudes will shift upwards by 3 for numbers less than 0.
