I am working with the chromatograms object from MSnbase. I used the chromatogram method with a set run time range and mz range in turn creating a large chromatograms object. I see that there is an S4 method for accessing data inside of the object but can not quite get it to work to pull the list of intensity values from the object. When I write the chromatograms object to a txt file, I can see that the data is there and can access it that way, with a lot a data cleaning along the way. Is there a way to access this intensity and rtime data directly from the large chromatograms object itself in R?
