RatioIntersect: RatioIntersect class

In adeschen/similaRpeak: Metrics to estimate a level of similarity between two ChIP-Seq profiles

RatioIntersect class

Description

An object which is a interface to calculate the ratio between the peaks values between two profiles.

The RatioIntersect object is needed to calculate the ratio of profiles intersection area between two profiles and those profiles total areas. A threshold and the two profiles are set during the RatioIntersect object creation. If different threshold or profiles are needed, the calculateMetric function should be used, with the new profiles and threshold passed as arguments to update those values inside the RatioIntersect object.

The threshold is the minimum total area value accepted to calculate a ratio.

Usage

RatioIntersect

Format

An object of class R6ClassGenerator of length 24.

Value

The RatioIntersect$new function returns a RatioIntersect object which contains the information about the two profiles and the threshold used to calculate the metric. It can be used, as many times needed, to calculate the specified metric.

Constructor

Create a RatioIntersect object.

RatioIntersect$new(profile1, profile2, threshold = 1)

The threshold is the minimum total area value accepted to calculate a ratio.

The RatioIntersect object inherites those functions:

• getMetric A function that returns the value of the calculated metric

• getInfo A function that returns a description of the metric with the metric value.

• getType A function that returns the unique name associated to this metric

• calculateMetric A function that modifies the values of the two profiles and the threshold. The new values (profile1, profile2, threshold) are passed as arguments.
