cosineSim {PANR} | R Documentation

## Compute cosine similarities or distances between pairs of genes

### Description

This function compute cosine similarities or distances between pairs of genes, given measured rich phenotypes.

### Usage

    cosineSim(x)
    cosineDist(x)

### Arguments

`x` | a numeric matrix of rich phenotypes with rows and columns specifying samples and genes, respectively.

### Value

This function will return either a numeric matrix of cosine similarities or an object of `dist`.
