rFIA v1.1.1
- Jeff Doser is the new package maintainer. Please send all inquiries
via email to Jeff (jwdoser@ncsu.edu) or post potential bugs on the
GitHub development page.
- Updated the
fiaRI
object to reflect recent changes in
the FIA Database. These changes resulted in the package functions
successfully working with the previous version of fiaRI
but
not working for actual user data when pulling data from recent versions
of the FIA Database.
- Updated functionality for working with external spatial
(
sf
) objects with the following functions:
tpa()
. Changes in recent versions of the sf
package led to errors when attempting to return a spatial object. This
bug is now fixed.
- Updated a substantial bug in
area()
and
areaChange()
that resulted in incorrect area (or area
change) estimates being reported when specifying treeDomain
and grpBy
(when using grouping variables from TREE). In the
previous version, the filters were not properly applied, and so area
estimates did not adequately represent the filtering conditions and
often just provided the same values as if treeDomain
was
not specified. Estimates now provide correct results that are more
inline with intuition. For example, if specifying
treeDomain = SPCD == 121
[i.e., longleaf pine], the
previous area()
function would essentially ignore this and
return area of all forest plots. Now, area()
will return
the estimate of land area where at least one longleaf pine tree occurs.
Further, the estimate of percent area will be the percentage of total
land area (which is determined by landType
) that contains
longleaf pine.
- Substantial updates to
biomass()
. Previous versions
were not compatible with updates in FIADB and the new National Scale
Volume and Biomass (NSVB) estimators. The function is now updated and
returns biomass and carbon estimates using the NSVB procedure.
- Updated
findEVALID()
to return the correct evaluation
IDs. Previous versions had an incorrect join that resulted in
additional, incorrect EVALIDs being returned for a given set of
criteria. This function should only be used by users familiar with FIA
and desiring to use FIA data for use outside of rFIA
, as
rFIA
is built in a way that users do not need to directly
interact with EVALIDs.
- Updated
dwm()
when byPlot = TRUE
to set
the YEAR
column equal to the year each plot was measured
(MEASYEAR
), which may differ slightly from its associated
inventory year (INVYR
). This is what all other
rFIA
functions do and what was reported in the manual, but
the YEAR
returned prior to this version was actually the
inventory year.
- Fixed a bug with
growMort()
that resulted in estimates
of mean annual survivor growth and mean annual net change reporting as
0.
- Fixed a discrepancy with
growMort()
calculation of
removals and the description of it in the manual. Removal estimates
provided by growMort()
do NOT include stems that grow
beyond the 5-inch diameter threshold and then are subject to harvest or
natural mortality before the remeasurement period. In other words,
rFIA
recruitment does not include trees corresponding to
FIA growth components of CUT2 and MORTALITY2.
- Fixed a typo in the
standStruct()
documentation that
incorrectly said the lower diameter for Pole class was set at 11cm while
it is in fact set at 12.7cm (5in).
- Fixed typo in documentation of
plotFIA()
regarding the
error bars produced when se = TRUE
. These are 95%
confidence intervals, not 68% confidence intervals.
- Added more details to
vegStruct()
on reporting of
estimates by canopy layer and growth habit.
- Updated internal data to now contain the Dec 2024
REF_SPECIES
table from FIADB, which provides access to the
CARBON_RATIO_LIVE
attribute for using the NSVB
species-specific carbon fractions.
- Updated all estimation functions to fix a bug that resulted in an
error when setting
method = 'EMA'
.
- Removed all references to “ECOSUBCD” in the help pages since this
column was removed from the PLOT table in FIADB v9.3.
- Updated
writeFIA()
to allow users to write database
tables by state when only a subset of the table is originally read into
R. This currently requires either the PLOT or COND tables to be read
in.
- Fixed a bug in
plotFIA()
that led to an error in
animated plots when gganimate
was not loaded (note that
gganimate
still needs to be installed).
