Function `d1char.d1nat`

is applied to a pair of vectors of characters or to a pair of 1d arrays of characters and generates then the pair of corresponding probability vectors by calling `d1nat`

function

1 | ```
d1char.d1nat(farr0, farr1, reject = c(""))
``` |

`farr0` |
vector of characters |

`farr1` |
vector of characters |

`reject` |
vector of rejected characters (the characters excluded from original vectors for analysis) |

First, it assigns the identification number for each individual character met in original vectors. Then it works similarly to `hist`

function but for the pair of samples with identification numbers as outcomes. It prints the decoding array (listing the identification numbers corresponded for each character) and, as a bonus, it prints basic statistics summary for distributions alongside with technical plot. It is recommended for use as a data preparation step before the following Klimontovich's S-theorem based analysis.

`f0 ` |
probability vector representing state0 of a system |

`f1 ` |
probability vector representing state1 of a system |

# step b. Compare samples with Klimontovich's S-theorem. Renormalized entropy indicates
# the opposite: s0 is more ordered and difference in Shannon
# entropy values was due to just "thermodynamic noise"
