Description
For a vector of given peak locations, quantify peaks for
individual spectra.
Usage
1
getPeaks2(bseoffM, pVec, eps = 0.003)
Arguments
bseoffM
A matrix of intensities, with rows the
m/z values and columns samples.
pVec
A vector of given peak locations.
eps
Relative precision of peak location.
Details
Each peak is expanded to an interval, eps * m/z to
the left and right of the peak. Intensities of
individual spectra are quantified by the maxima
in this interval.
Value
A matrix of intensities with rows the peaks 'pVec' and
column the samples. The m/z values of 'pVec' is stored
as the 'rownames' of the returned matrix.
