Group Peaks via High Resolution Alignment<br />
Description<br />
Runs high resolution alignment on single spectra samples stored in a given xcmsSet.<br />
Arguments<br />
object<br />
mzppm<br />
mzabs<br />

minfrac<br />
a xcmsSet with peaks<br />
the relative error used for clustering/grouping in ppm (parts per million)<br />
the absolute error used for clustering/grouping<br />
set the minimum number of samples in one bin<br />
