Guess the data type of a vector

Description

Guess the data type of a vector

Usage

prep_robust_guess_data_type(x, k = 50, it = 200)

Arguments

x	a vector with characters
k	numeric sample size, if less than ⁠floor(length(x) / (it/20)))⁠, minimum sample size is 1.
it	integer number of iterations when taking samples

Value

a guess of the data type of x. An attribute orig_type is also attached to give the more detailed guess returned by readr::guess_parser().

Algorithm

This function takes x and tries to guess the data type of random subsets of this vector using readr::guess_parser(). The RNG is initialized with a constant, so the function stays deterministic. It does such sub-sample based checks it times, the majority of the detected datatype determines the guessed data type.
