#I would like to interpolate a straight line between 06/08/06 04:16:00 -
06/08/06 20:31:00 with values and then sum them. This is an estimate of
ecosystem #respiration and I will be using this in a larger context(48 days
of these diurnal curves), but for right now I am just trying to figure out
Try this using your z and library(zoo):
# extract section of interest
w - window(z, start=chron(6/8/6, 4:16:0), end=chron(6/8/6, 20:31:0))
# zap all interior points with NA's and then fill back in using linear
interpolation
lin - na.approx(replace(w, time(w) start(w) time(w) end(w), NA))
