PICset.align | R Documentation |
This function is used to calculated the shifts of PICs in each group, and correct the retention times of the peakmat and picset obtain by PICset.group
function.

move |
Which method is used to move the original to new position. can be 'direct' or 'loess'. 'direct' means directly move each PIC based on the calculated shift. 'loess' means use a loess regression to the obtained shift and predict a new shift of each PIC, then move each PIC based on the new values. |
