Hi, fp is a data frame like this
,----[ fp ] | Frequenz AmpNorm | 1 3322 0.0379490639 | 2 3061 0.0476033058 | 3 2833 0.0592954124 | 4 2242 0.1275510204 `---- i want to find the "Frequenz" where "AmpNorm" is max. I use this line as workaround: PeakFreqHz = subset(fp, AmpNorm == max(AmpNorm))$Frequenz[1] Is there something nicer? And is there an easy way to do the same on "predict()" Thank you and kind regards, -- Jonas Stein <n...@jonasstein.de> ______________________________________________ R-help@r-project.org 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.
