The package exposes 5 tightly interconnected tibbles:
INFCspecies
, INFCcatalog
, Quantities
, INFCparam
, INFCf_domains

Tables columns
INFCspecies
EPPOcode [PK]
: species code, adopting EPPO database
pag
: section page number in the original reference (Tabacchi et al., 2011a)
PrefName
: EPPO preferred name for the species
INFCcatalog
pag [PK]
: section page number in the original reference (Tabacchi et al., 2011a)
n_oss
: number of sample trees for the section
n_par
: number of parameters in the equations for the section
section
: section name (species or species group)
Quantities
quantity [PK]
: code of the estimated quantity
quantity_definition
: estimated quantity definition and measurement units
INFCparam
pag [PK]
: section page number in the original reference (Tabacchi et al., 2011a)
quantity [PK]
: code of the estimated quantity (see Quantities)
wrv
: weighted residual variance
bm
: functions coefficients (a list of arrays)
vcm
: variance-covariance matrices (a list of 'dspMatrix')
INFCf_domains
pag [PK]
: section page number in the original reference (Tabacchi et al., 2011a)
htot.m [PK]
: tree height class [m] (class width 1 m)
dbh.min
: minimum tree diameter class [cm] (class width 1 cm)
dbh.max
: maximum tree diameter class [cm] (class width 1 cm)
Columns bm
and vcm
are lists, the dimensions of the arrays and
matrices they store vary depending on n_par
.
Matrices in vcm
are symmetric, stored as "dspMatrix" class objects.
Database schema is defined, verified and illustrated using package dm
library(dm)
