## Piecewise linear transformation for distance matrices

### Description

Piecewise linear transformation for distance matrices, utility function for `geco`.

### Usage

    piecewiselin(distmatrix, maxdist=0.1*max(distmatrix))

### Arguments

`distmatrix` | symmetric (non-negative) distance matrix.
`maxdist` | non-negative numeric. Larger distances are transformed to constant 1.

### Details

Transforms large distances to 1, 0 to 0 and continuously linear between 0 and `maxdist`.
