dist_by_closeness {EnrichedHeatmap} | R Documentation

## Distance by closeness

### Description

Distance by closeness

### Usage

    dist_by_closeness(mat)

### Arguments

`mat` | a numeric matrix where the distance is calculated by rows

### Details

For two rows in the matrix, assume x_1, x_2, ..., x_n1 are the column index of none-zero values in row 1 and y_1, y_2, ... y_n2 are the column index for non-zero values in row 2, the distance between the two rows based on the closeness is calculated as:

d_closeness = sum_i sum_j(|x_i - y_j|) / (n_1*n_2)

### Value

A `dist` object

### Examples

    x1 = c(0, 0, 0, 0, 1, 1, 1, 0, 0, 0)
    x2 = c(0, 0, 0, 1, 1, 1, 0, 0, 0, 0)
    x3 = c(1, 0, 0, 0, 1, 1, 0, 0, 0, 0)
    m = rbind(x1, x2, x3)
    dist(m)
    dist_by_closeness(m)
