Select Matching Ids as Anchors

Description

This is an optional helper function for selectAnchors. Uses identities to guide selection of ordered retention time pairs. If useID option is set to TRUE, it will select pairs of features with matching ID character strings before proceeding with iterative anchor selection.

Usage

identityAnchorSelection(cTable, windx, windy, useID, brackets)

Arguments

cTable

data frame, contains only feature ids, mzs, rts, Qs, & labels

windx

numeric positive retention time exclusion window in X dataset

windy

numeric positive retention time exclusion window in Y dataset

useID

logical. Operation proceeds if TRUE, terminates otherwise.

brackets

If useID = TRUE, bracketed identity strings of the types included in this argument will be ignored

Details

Identity anchors are allowed to violate constraints of m/z, Q, and rtq difference tolerances, and will not be removed if they fall within a rt exclusion window of other features. If a name appears more than once, only the pair with the highest relative abundance is selected.

Value

combinedTable with updated anchor labels
