Hi, I have a large number of high performance liquid chromatography (HPLC) datafiles that I was hoping to process using R. I couldn't find anything in the mailing list archives or the packages list but before I go around reinventing the wheel, has anyone on the list got any pointers or code they are willing to share for identifying peaks, fitting a baseline and calculating peak areas?
