gr.raw {CTFS} | R Documentation |
Computes the annual dbh increment for each tree and compares it to an
expected range of values based on the function
trim.growth
. The range of values is set so high and low
as to include all possible growth rates (or so it is believed). This
function is intended for use by biomass
but can be used
by itself if unadjusted, raw DBH increments for individuals trees is
desired.
gr.raw(census1, census2, rounddown = FALSE)
census1 |
name of census datafile for first census, must be a
dataframe, must be of same length as census2 |
census2 |
name of census datafile for second census, must be a
dataframe, must be of same length as census1 |
rounddown |
logical value in caps. When TRUE, if either of
census is < 55, then the floor of the dbh value / 5 is
provided. When FALSE, no change in the dbh is made. |
See CTFS.growth
for details on the computation methods
of growth rates and associated functions.
Any two censuses on a datafile must be used. They do not have to be
sequential, only that census1
has to be before census2
.
The results of gr.raw
are annual DBH increments for individual
trees, NOT MEAN GROWTH VALUES. A value is returned for
each tree. No invalid values should result but this means that no
reasonable trimming of growth rates has been done.
gr.raw
returns a vector of annual dbh increments. It is not
intended for use outside of biomass
but it will function
on its own.
If you want the annual dbh increments for individual trees with the
full compliment of computed values, use growth.indiv
.
