callBafChanges: Call sites showing BAF changes
In tkonopka/RGeneticThesaurus: Analysis of thesaurus-annotated genomic variants

This function performs very crude mutation calling based on BAFs. The calling is depends only on fold change and minimum AF thresholds.

1 2	callBafChanges(baftable, cref, csample, foldchange = 1.2, maxref = 0.05, minAF = 0.15)

`baftable`	data.frame with variants and allelic frequencies
`cref`	identifier for column with reference BAF (e.g. normal tissue)
`csample`	identifier for column with matched sample BAF (e.g. tumor tissue)
`foldchange`	minimum fold.change threshold to call mutation
`maxref`	numeric, maximum allowed BAF in the reference sample
`minAF`	numeric, minimum BAF required in the sample
