hex2bin(hex, ignore = ":")
random(n = 1)

Arguments

bin

raw vector with binary data to convert to hex string

hex

a string with hexadecimal characters to parse into a binary (raw) vector.

ignore

a string with characters to ignore from hex. See example.

n

number of random bytes or numbers to generate

Examples

# Convert raw to hex string and back
test <- charToRaw("test 123")
x <- bin2hex(test)
y <- hex2bin(x)
stopifnot(identical(test, y))
stopifnot(identical(x, paste(test, collapse = "")))

# Parse text with characters
x2 <- paste(test, collapse = ":")
y2 <- hex2bin(x2, ignore = ":")
stopifnot(identical(test, y2))
