cos_sim {MutationalPatterns} | R Documentation

## Cosine similarity function

### Description

Calculate the cosine similarity between two vectors of the same length. The cosine similarity is a value between 0 (distinct) and 1 (identical) and indicates how much two vectors are alike.

### Usage

    cos_sim(x, y)

### Arguments

`x` | Vector 1 of length n
`y` | Vector 2 of length n

### Value

Cosine similarity value; a value between 0 and 1

### Examples

    x = c(1.1, 2.1, 0.2, 0.1, 2.9)
    y = c(0.9, 1.9, 0.5, 0.4, 3.1)
    cos_sim(x, y)
