Hash R objects with numeric rounding (digest's sha1 generic, natively)

Source: R/digest_native.R
morie_sha1.Rd

Doubles are written as hexadecimal mantissa/exponent with digits significant digits and zapsmall small-value flooring, so that the hash is the same across platforms; every method and attribute rule of digest::sha1() is reproduced.

Usage

morie_sha1(x, digits = 14L, zapsmall = 7L, ..., algo = "sha1")

Arguments

x

the object.

digits, zapsmall, algo, ...

as in digest.

Value

the hex digest.

Examples

morie_sha1(c(1.1, 2.2, pi))
#> [1] "49450d33079178d1bd94deb16ad837dea96ec543"
morie_sha1(data.frame(a = 1:3, b = c("x", "y", "z")))
#> [1] "94e9463c086dcba7aea01ff4991d7ec8fcc8c55e"
