Bytes formatter: convert to byte measurement and display symbol.

Bytes formatter: convert to byte measurement and display symbol.

byte_format(symbol = "auto", units = "binary", only_highest = TRUE)

Kb(x)

Mb(x)

Gb(x)

bytes(x, symbol = "auto", units = c("binary", "si"),
  only_highest = FALSE)

Arguments

symbol	byte symbol to use. If "auto" the symbol used will be determined by the maximum value of x. Valid symbols are "b", "K", "Mb", "Gb", "Tb", "Pb", "Eb", "Zb", and "Yb", along with their upper case equivalents and "iB" equivalents.
units	which unit base to use, "binary" (1024 base) or "si" (1000 base) for ISI units.
only_highest	Whether to use the unit of the highest number or each number uses its own unit.
x	a numeric vector to format

Value

a function with three parameters, x, a numeric vector that returns a character vector, symbol a single or a vector of byte symbol(s) (e.g. "Kb") desired and the measurement units (traditional binary or si for ISI metric units).
