plots.swo {rconifers} | R Documentation |
This a simple plot file data.frame
that contains basic plot attributes used in the CONIFERS growth model, corresponding to the plants.swo dataframe.
The plots.swo
data frame has 4 rows and 6 columns.
data(plots.swo)
This data frame contains the following columns:
The example plot data represents plot level observations for
a field sample that can be used to generate future forest conditions
using the CONIFERS forest growth model. The data are in imperial
units. The required values are the plot
, elevation
, and
slope
, and aspect
measurements. Values that have not
been observed, or are missing (e.g. whc and map), are denoted with an
NA
and can be imputed using the impute
function,
which the exception of the si30
. The current version of the
library does not include the functions to compute si30
from
tree observations in the impute
function.
