## Calculate isotope distance matrix from xsAnnotate object

### Description

Processing an xsAnnotate object with annotated isotopes (findIsotopes). It return a weighted edge list as distance matrix between peaks according to the isotope annotation. The edge value for recognized isotopes is 1 for all cases. The list can be used as input for `calcPC`.

### Arguments

`object` | `xsAnnotate` object

### Value

A matrix with 4 columns:

`x` | peak index
`y` | peak index
`cor` | edge value, always 1
`ps` | pseudospectrum index, which contains x and y

### Methods

object = "xsAnnotate"

  `calcIsotopes(object)`
