In michaelwitting/masstrixR: Annotation of MS based metabolomics data

Description Usage Arguments Author(s) See Also Examples

This functions is used to check of two measured masses are different by a give mass difference. This can be used to check if a neutral loss is found between two masses or if masses are connected by certain metabolic transformations, e.g. methylation, acetylation etc.

1	matchMassDiff(mz1, mz2, mzDiff, mzTol = 0.005, mzTolType = "abs")

`mz1`	First m/z value for which a mass difference shall be checked
`mz2`	Second m/z value for which a mass difference shall be checked
`mzDiff`	Mass difference to check for
`mzTol`	m/z error, numeric value
`mzTolType`	type of error used, absolute (abs) or relative (ppm)
