Interpolate plant properties using the 'b90' method

Creates a daily sequence for one year from parameters.

plant_b90(
  minval_before_incr,
  minval_after_decr = minval_before_incr,
  maxval,
  doy.incr,
  incr.dur,
  doy.decr,
  decr.dur,
  maxdoy
)

Arguments

minval_before_incr: Minimum value used for the time period before doy.incr.
minval_after_decr: Minimum value used for time period after doy.decr.
maxval: Maximum value.
doy.incr: Day of year when increasing from minval_before_incr to maxval starts.
incr.dur: Duration (number of days) since doy.incr until maxval is reached.
doy.decr: Day of year when decreasing to minval_after_decr begins.
decr.dur: Duration (number of days) since doy.incr until minval_after_decr is reached.
maxdoy: Length of the year (366 for leap years).

A numeric vector of length maxdoy.

plot(plant_b90(minval_before_incr = 0,minval_after_decr = 0.2,
maxval=1,
doy.incr = 121,incr.dur = 28,
doy.decr = 280, decr.dur = 50,
maxdoy = 365))
