Update feature mz/rt using peak-intensity weighted means

xcms_get_feature_wmean.Rd

Recomputes mzmed and rtmed in xcms::featureDefinitions(xcms.xcms) using peak-level mz/rt weighted by peak maxo (maximum intensity) from xcms::chromPeaks(xcms.xcms).

Usage

xcms_get_feature_wmean(xcms.xcms)

Arguments

xcms.xcms

An xcms::XCMSnExp object with feature definitions and chromPeaks.

Value

An updated xcms::XCMSnExp object where featureDefinitions(object)$mzmed and featureDefinitions(object)$rtmed are replaced by the intensity-weighted means across each feature's constituent peaks.
