Human readable memory sizes

Source: R/bytes.R

Construct, manipulate and display vectors of byte sizes. These are numeric vectors, so you can compare them numerically, but they can also be compared to human readable values such as '10MB'.

  • parse_bytes() takes a character vector of human-readable bytes and returns a structured bytes vector.

  • as_bytes() is a generic conversion function for objects representing bytes.

Note: A bytes() constructor will be exported soon.

as_bytes(x)

parse_bytes(x)

Arguments

x

A numeric or character vector. Character representations can use shorthand sizes (see examples).

Details

These memory sizes are always assumed to be base 1024, rather than 1000.

Examples

parse_bytes("1")
#> [1] 1B
parse_bytes("1K")
#> [1] 1KB
parse_bytes("1Kb")
#> [1] 1KB
parse_bytes("1KiB")
#> [1] 1KB
parse_bytes("1MB")
#> [1] 1MB

parse_bytes("1KB") < "1MB"
#> [1] TRUE

sum(parse_bytes(c("1MB", "5MB", "500KB")))
#> [1] 6.49MB
