ppc.peak.summary {ppc} | R Documentation |
This function produces a summary of peaks from a PPC analysis
ppc.peak.summary(centroid.fit, peak.fit, data, user.parms, split.fit)
centroid.fit |
Result of call to ppc.make.centroid.list |
peak.fit |
Result of call to ppc.predict.peaks |
data |
List containing mass spec data |
user.parms |
List of user defined parameters |
split.fit |
Result of call to ppc.find.splits |
Matrix containing on row per peak. Columns are peak.position, min, max of peak.position, number.of.spectra in which the peak occurs, rank.of.peak, in discriminatory power, split point for peak height, proportion of samples in class 1 exceeding split point, proportion of samples in class 2 exceeding split point etc, pairwise differences in these probabilities, peak info for each sample
