lowess + turnpoints = doubling integers?
...he smoothed result as well as turnpoints (using yy$tppos) on top of raw
data plot.
Result is exactly as expected, graphically.
For another purpose, I calcuate the difference between turnpoints (representing
time intervals between turnspoints in my applicaiton), e.g.
aduration[j]<-yy$tppos[i+1]-yytppos[i]
This also appears to work as expected, HOWEVER, a typical list of such
differences looks like:
22,33,22,11,33,44,33,33,11,33,44,66,33,22,.........
there are, in some instances, three digit measure such as 110 or 106, etc. but
the double-digit measures, although of the proper magnitude, seem to...
