correlate: Calculates correlation between vectors shifted by titrations.

In Swarchal/TISS: Titration Invariant Similarity Score

Description

For a matrix, with each row representing a compound vector constructed of features and titrations. correlate will calculate the correlation for each vector compared against the average of all the other vectors, shifted by a number of titrations in both directions. This is to align compound vectors invariant of differing potencies.

Usage

correlate(x, metadata, return_max = TRUE)

Arguments

x	Matrix or dataframe of compound vectors. Each column representing an individual compound vector. This should have been produced by
metadata	corresponding metadata for x, produced by calculate_d and scaled with scale_d construct_metadata
return_max	Boolean. If TRUE, then will only return the shift that produced the maxmimum correlation. If return_max = FALSE, it will return all shifts and their associated correlations.

Value

List of correlation measurements, each element of the list corresponds to a compound vector in the order given by x
