CAMERA / slot neutraladdition can not be empty to use generateRules
I try the following:
> rsP <- new("ruleSet")
> rsP@ionlistfile <- "ions_pos.csv"
> rsP@neutraladditionfile <- "neutraladdition.csv"
> rsP@neutrallossfile <- "neutralloss.csv"
> rsP <- readLists(rsP)
> rsP <- setDefaultParams(rsP)
> rsP <- generateRules(rsP)
Fehler in if (neutraladdition[i, 1] == "NaCOOH") { :
  Fehlender Wert, wo TRUE/FALSE nötig ist

which is because neutraladdition.csv just has the header and no entries which creates an empty slot of neutraladdition. I do not want to allow a neutral addition in my rule set. Is there a possibility to fix that? I guess the problem is in the section "## Erzeuge Neutral" of ruleSet.R

Many Thanks,
Andre

CAMERA / possible bug in plotEICs
plotEICs(anP.group.iso.corr.add, pspec=2, maxlabel=5) results in https://www.dropbox.com/s/4ovljepz1c99q7u/maxlabel5.eps

and plotEICs(anP.group.iso.corr.add, pspec=2, maxlabel=10) results in https://www.dropbox.com/s/56aiv7ltkczfv ... abel10.eps

As you can see the color labels are pointing to different peaks in the two versions of the same spectra.
