Maxima are found if I prolong the 1-cycle time series on both sides, appaently no matter which values I use.
The following sequence works fine:

     aal  <- rep (aa[1], length(aa))
     aar  <- rep (aa[length(aa)], length(aa))  
     aa3 <- c(aal,aa,aar)                                                                       #APPEND CYCLE TO ITSELF TWICE 
     aa3ts <- create.signalSeries(aa3, pos=list(from=0.0, by=0.033))  #CONVERT AMPLITUDE INTO TIME-SERIES 
     plot (aa3ts, main=paste(insig," Cycle: ",j,sep=""))        
     aa3.cwt <-  wavCWT(aa3ts)                                                 #CWT
     aa3.maxtree <- wavCWTTree (aa3.cwt, type="maxima")    # GENERATE CWT MAXIMA TREE
     aa3.maxpeak <- wavCWTPeaks (aa3.maxtree)                    #GET MAXIMUM PEAK

Since the minima of  aa are the maxima of -aa I reverse the sign and then repeat the above procedure.
The following sequence works fine:

## EXCHANGE MAXIMA WITH MINIMA
      bb  <-  -aa                                                                                     #REVERSE SIGN
      bbl  <- rep (bb[1], length(bb))\
      bbr  <- rep (bb[length(bb)], length(bb))  
      bb3 <- c(bbl,bb,bbr)                                                                      #APPEND CYCLE TO ITSELF TWICE 
      bb3ts <- create.signalSeries(bb3, pos=list(from=0.0, by=0.033))  #CONVERT AMPLITUDE INTO TIME-SERIES 
      plot (bb3ts, main=paste(insig," Cycle: ",j,sep=""))        
      bb3.cwt <-  wavCWT(bb3ts)                                                #CWT
      bb3.maxtree <- wavCWTTree (bb3.cwt, type="maxima")   #GENERATE CWT MAXIMA TREE
      bb3.maxpeak <- wavCWTPeaks (bb3.maxtree)                    #GET MAXIMUM PEAKS 

It looks like wmTSA functions work like the Moving Average algorithm  which uses a portion of the time series 
for kind of self-training ....

Best regards,
Maura

I'm stumped.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
