Dear All, I have a data frame with the columns "Mass" and "Intensity" (this is mass spectrometry stuff). Each of the mass values gives rise to a mass window of 5 ppm around the individual mass (from mass - mass/1E6*5 to mass + mass/1E5*5). I need to filter the array such that in case these mass windows overlap I retain the mass/intensity pair with the highest intensity. I apologize for this question, but I have no formal IT education and would value any nudges toward favorable algorithmic solutions highly.
Thanks for any help, Joh ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
