Peptides are encoded using the BLOSUM62 probability matrix (See BLOSUM62_PROB data matrix)

1 | ```
pep_encode(pep)
``` |

`pep` |
A character vector of peptides to be encoded |

Each position in the peptide become a vector of 20 values, corresponding to the rounded log odds ratio for substituting the amino acid in the peptide with each of the 20 standard proteogenic amino acids.

The final result is a 3D array (tensor) of peptide 'images' with `n`

rows, `k`

columns and `20`

slices, which is stored as a 3D array (tensor)

A 3D array (tensor) of peptide 'images'

1 2 | ```
pep_encode(pep_ran(k=9,n=10))
dim(pep_encode(pep_ran(k=9,n=10)))
