asSize: convert numeric value to size

In jmw86069/jamba: Jam Base Methods

convert numeric value to size

Description

convert numeric value to size

Usage

asSize(
  x,
  humanFriendly = TRUE,
  digits = 3,
  abbreviateUnits = TRUE,
  unitType = "bytes",
  unitAbbrev = gsub("^(.).*$", "\\1", unitType),
  kiloSize = 1024,
  sep = " ",
  ...
)

Arguments

x	numeric vector
humanFriendly	logical, currently only TRUE is accepted, whether to include human-friendly units to the output.
digits	integer number of digits used by format when formatting the number to create a character string
abbreviateUnits	logical whether to print abbreviated units, for example using k, M, G, T, P instead of kilo, mega, Giga, Tera, Peta, respectively.
unitType	character string indicating the base unit of measure, by default "bytes". Note that trailing "s" is removed when the number is singular.
unitAbbrev	character string indicating an abbreviated base unit, by default it uses the first character from unitType.
kiloSize	numeric number of base units when converting from one base unit, to one "kilo" base unit. For file sizes, this value is 1024, but for other purposes this value may be 1000.
sep	delimiter used between the numeric value and the unit.
...	other parameters passed to format.

Details

This function is intended to provide the inverse of asSize() by converting an abbreviated size into a full numeric value.

It makes one simplifying assumption, that the first character in the unit is enough to determine the unit. This assumption also means the units are currently case-sensitive.

Value

character vector representing human-friendly sizes.

Examples

asSize(c(1, 10,2010,22000,52200))
#> "1 byte"   "10 bytes" "2 kb"     "21 kb"    "51 kb"

# demonstration of straight numeric units
asSize(c(1, 100, 1000, 10000), unitType="", kiloSize=100)
