Description

Bibliography
Description
Estimates biomass, carbon and nitrogen of moss and lichen ground
layers as part of the US Forest Service Forest Inventory and
Analysis program.
Datasets
cal is calibration data from destructive
sampling.
est is estimation data from nondestructive
sampling at sites where estimates are desired.
Functions
check_dat checks that estimation data are in
proper format.
calc_biomass is the core function to calculate
ground layer metrics (prominently including biomass).
summary_plot produces summaries at the
plot-level, the expected level of summarization for USFS-FIA.
summary_fg produces summaries at the level of
functional groups.
plot_map plots a map of geographic locations
colored by some value.
plot_facet plots a scatterplot or histogram of
values faceted by some grouping variable (such as functional
groups).
