CAMERA / plotPsSpectrum error
Hi Everyone,

Just wondering if anyone has encountered an error while trying to plot a pseudospectra. plotEICs works just fine but plotPsSpectrum does not. The codes and error are posted below. Thanks in advance

xset6 = xsAnnotate(xset5)
xset7 = groupFWHM(xset6, perfwhm = 0.6)
xset8 = groupCorr(xset7, cor_eic_th=0.75, pval=0.05, calcCiS = TRUE)
xset9 = findIsotopes(xset8)
xset10 = findAdducts(xset9, polarity="positive")

plotEICs(xset10, pspec=6, maxlabel=5)

plotPsSpectrum(xset10, pspec=6, maxlabel=5)

Error in if (!is.numeric(index) && index > length(sampnames(xs)) | index <  :
  missing value where TRUE/FALSE needed

Cheers,
Mike

XCMS / using plotPeaks to plot selected peaks
Hi all,

I used plotPeaks to plot my xraw but it is only showing for the first few m/z. How do I set it to plot a peak that I am interested in.

This is what I use: mypeaks = findPeaks.matchedFilter(xraw, snthresh=10, step=0.1, steps=2))
                            plotPeaks(xraw, mypeaks, figs=c(2, 2))

Thanks for your help in advance.
