## Class `"MasterPeptides"`

### Description

A class to store the results of `makeMaster`. This class stored the 2 versions (orders) of the master final peptide data.

### Objects from the Class

Objects can be created by calls of the form `makeMaster`.

### Slots

`masters`:

  Object of class `"list"` storing the 2 master `data.frame` objects.

`pepfiles`:

  Object of class `"character"` with the list of final peptide input files.

`fdr`:

  Object of class `"numeric"` with the peptide false discovery applied when creating the filter.

`method`:

  Object of class `"character"` with the peptide p-value adjustment method. One of `BH` (default), `qval` or `Bonferroni`.

`orders`:

  Object of class `"list"` with the `numeric` vectors specifying the order of `pepfiles` used to generate the respective `masters` `data.frames`.

`fragmentfiles`:

  Object of class `"character"` with the list of final fragment input files.

`fragments`:

  Object of class `data.frame` storing the combined final fragment data.
