| combineMolIon | R Documentation |
This function combines ion annotations in different acquisition modes. It operates in two main modes, combining individual annotations given by get.annot function, using the retention time and mass/charge windows provided by the user or extracting annotations from a peak table provided by CAMERA's combinexsAnnos function.
combineMolIon(antPOS, antNEG, peaklist = NULL,
cameraobj = NULL, polarity = NULL, rtwin = 5,
mzwin = 0.05)
antPOS |
positive annotation list given by get.annot. |
antNEG |
negative annotation list given by get.annot. |
peaklist |
given by CAMERA's combinexsAnnos function. If this option is chosen the user has to set the acquisition mode to the same as in CAMERA's function, and provide the respective object for downstream analysis. |
cameraobj |
xsAnnotate object for downstream analysis. |
polarity |
the same CAMERA's function acquisition mode. |
rtwin |
retention time window to annotate a peak as present in both acquisition modes. |
mzwin |
mass to charge ratio window to annotate a peak as present in both acquisition modes. |
a list with a matrix of possible molecular ions with a trace of their annotation and the respective xsAnnotate object.
