## Arguments

data |
a data frame that contains at least grouping identifiers (precursor, peptide or
protein) and p-values derived from any statistical test. |

grouping |
a character column in the `data` data frame that contains either precursor,
peptide or protein identifiers. For each entry in this column there should be one unique p-value.
That means the statistical test that created the p-value should have been performed on the
level of the content of this column |

pval |
a numeric column in the `data` data frame that contains p-values. |

## Value

A histogram that shows the p-value distribution.
