I should have been more careful, but I accidentally included a file that failed to inject when I ran the xcmsSet command. When I tried to perform retcor() later in the script, my failed injection is mucking things up because there are too few peak groups. Is there some way to remove a specific sample from an xcmsSet() object and keep all the others?
