findFragments {MassArray} | R Documentation |
Function to identify which fragment(s) in a list of fragments match a given molecular weight
findFragments(MW, fragments, resolution = 1)
MW |
Molecular weight target (in Da) |
fragments |
List of molecular weights corresponding to unique fragments |
resolution |
Resolution (in Da), used to specify the ability to distinguish two different molecular weights. For a resolution of 1 (default), two molecular weights are considered identical if they are less than 1 Da apart. |
Returns the index or indices of fragment(s) within the input list that have a molecular weight which matches that specified as input
