dotProdSpectra: dot product calculation
In adductomicsR: Processing of adductomic mass spectral datasets

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.

1 2	dotProdSpectra(adductSpectra = NULL, nCores = NULL, minDotProdSpec = 0.8, maxGroups = 10)

`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.
