## similaRpeak: Metrics to estimate a level of similarity between two ChIP-Seq profiles

### Description

This package is calculating six differents metrics to estimate a level of similarity between two ChIP-Seq profiles.

### Details

The `similarity` function calculates six differents metrics:

- RATIO_AREA: The ratio between the areas. The larger value is always divided by the smaller value.

- DIFF_POS_MAX: The difference between the maximal peaks positions. The difference is always a positive value.

- RATIO_MAX_MAX: The ratio between the maximal peaks values. The larger value is always divided by the smaller value.

- RATIO_INTERSECT: The ratio between the intersection area and the total area.

- RATIO_NORMALIZED_INTERSECT: The ratio between the intersection area and the total area of two normalized profiles. The profiles are normalized by divinding them by their average value.

- SPEARMAN_CORRELATION: The Spearman's rho statistic between profiles.

The function `similarity` also reports basic information about each ChIP profile such as the number of positions, the area, the maximum value and the position of the maximum value.
