This function computes cummulative sums of time-series replicates.
Usage
scacum(x, y = NA, z = NA)
Arguments
x
numeric vector of time-series replicates with names
of the vector being time units.
y
constant, or vector if the processed time-series
replicates have several levels, to scale the
computed cumulative values. If NA then the
computed cumulative sums are not scaled.
z
NA, or numeric constant. Reference
time(s) in range(s) of the vector names to scale the
cumulative values. If NA then maximum value in the
time-units range is used.
Value
Details
Cummulative sums of time-series replicates
(e.g. tree-radial increments) are scaled on reference constants
(e.g. individual tree diameters).
