For each position within the matrix of aligned sequences, the probability corresponding to each nucleotide is estimated. Missing values are imputed to a multistate nucleotide with probabilities corresponding to the frequency of each nucleotide in the corresponding organism.

1 | ```
missing.fun(x, symbols, R, Prob)
``` |

`x` |
Position k of the training set (a set of aligned nucleotide sequence) |

`symbols` |
Number of each nucleotide |

`R` |
Number of missing values for position |

`Prob` |
Probability of each base within genome |

This function is included on probability function. Missing.fun has to be different NULL
