dotProdSpectra {adductomicsR} | R Documentation

## dot product calculation

### Description

hierarchical clustering (complete method see `hclust`). Dissimilarity metric based on 1-dot product spectral similarity. Retention time and mass groups are therefore further subdivided based on spectral similarity. If outlying mass spectra have been erroneously grouped then these will be reclassified.

### Usage

    dotProdSpectra(adductSpectra = NULL, nCores = NULL,
    minDotProdSpec = 0.8, maxGroups = 10)

### Arguments

`adductSpectra` | AdductSpec object
`nCores` | numeric the number of cores to use for parallel computation. The default is to use 1 core.
`minDotProdSpec` | numeric minimum dot product score
`maxGroups` | numeric maximum number of groups to include from the dendrogram.

### Value

adductSpectra AdductSpec object
