Description Arguments Details Value Methods Note See Also
For each sample, identify peak groups where that sample is not represented. For each of those peak groups, integrate the signal in the region of that peak group and create a new peak.
After peak grouping, there will always be peak groups that do not include peaks from every sample. This method produces intensity values for those missing samples by integrating raw data in peak group region. In a given group, the start and ending m/z values for integration are defined by the median start and end points of the other detected peaks.
xcmsSet objects with filled in peak groups.
In contrast to the
fillPeaks.chrom method the maximum
intensity reported in column
"maxo" is not the maximum
intensity measured in the expected peak area (defined by columns
"mzmax"), but the largest intensity of mz
value(s) closest to the
"mzmed" of the feature.
