Strictly not for use in statistical analysis. Non-reproducible and with unknown statistical properties. Provides an alternative source of randomness from the Mbed TLS library for purposes such as cryptographic key generation. Mbed TLS uses a block-cipher in counter mode operation, as defined in NIST SP800-90A: Recommendation for Random Number Generation Using Deterministic Random Bit Generators. The implementation uses AES-256 as the underlying block cipher, with a derivation function, and an entropy collector combining entropy from multiple sources including at least one strong entropy source.
random(n = 1L, convert = TRUE)[default 1L] integer random bytes to generate.
[default TRUE] logical FALSE to return a raw vector, or TRUE to return the hex representation of the bytes as a character string.
A length 'n' raw vector, or length one vector of '2n' random characters, depending on the value of 'convert' supplied.
If 'n' is non-integer, it will be coerced to integer; if a vector, only the first element will be used.
Results obtained are independent of and do not alter the state of R's own pseudo-random number generators.
