get.annot | R Documentation |
This function extracts annotation from CAMERA object, generating a matrix of non-redundant putative molecular ions.
get.annot(xsAnnotate, polarity = "positive", allowMiss = FALSE, xset = NULL, toexclude = NULL, minsamp = 0.6, minint = 5000)
xsAnnotate |
CAMERA's annotation object. |
polarity |
acquisition mode of mass spectrometer. |
allowMiss |
logical, optionally retrieves peaks with no evidence of adduct or isotope and annotate them as single charged molecules [M+/-H]. |
toexclude |
samples to be excluded of peak counting to non-annotated peak selection. |
xset |
xcmsSet xcms object after missing data replacement, to retrieve SNR to isotopic peaks. |
minsamp |
minimum number of samples in which an ion should be present to be selected. |
minint |
minimum mean intensity that a ion should present to be selected. |
A list with a matrix of possible molecular ions with a trace of their annotation, and the used xsAnnotate object.
