TapeS 0.13.2

• in tprVolume now checking lower end ‘A’ of segment against upper end ‘B’ of segment: ‘A’ should be lower or equal ‘B’. This is especially important if one of both is given as a diameter and the other as a height.
• bug fix in uncertainty estimation of biomass for deciduous trees and requested component ‘ndl’.

TapeS 0.13.1

• extended internal function which calculated position and length of measurement position during volume estimation: now parameter AB in tprVolume can both be zero with no error and returning reasonable information: 0.

TapeS 0.13.0

• implemented variance estimates for biomass estimates, based on the NSUR component biomass functions. See details in tprBiomass-helpfile for how this was done.
• added function nsur2() implementing the ‘simple’ biomass functions of Vonderach et al. 2018 (internal).
• corrected function nsur(), now using the adjusted tree height (tree height minus stump height) for prediction as detailed in Vonderach & Kändler (2021)
• bugfix in internal nsur()-function: one parameter in ash was wrong (led to negative estimates in small trees).
• extended tprBiomass: now optionally scale NSUR- to NFI-estimate
• moved internal data to sysdata instead of data/, hence, package runs also if not attached (e.g. calls via TapeS::tprVolume don’t break)
• added citation file
• corrected minor bugs, some internal improvements

TapeS 0.12.1

• corrected bug in example of nsur() function

TapeS 0.12.0

• function tprVolume now with MSE and interval information
• function tprDiameter now returns estimated MSE for the mean and prediction when interval=‘MSE’
• added ‘sHt’ into tprObject
• added function FormTariff() to fix taper form according to German NFI observations instead of giving a second measured diameter
• added ‘inv’-parameter into tprTrees-constructor
• corrected component biomass function, now total mass includes needle mass
• improved plotting function
• improved documentation

TapeS 0.11.2

• updated the relative taper models for beech, oak and red oak, adding a lower diameter to the relative data based on BDAT to stabilise taper curves.

TapeS 0.11.1

• small adjustements

TapeS 0.11.0

• added new TapeR-models for beech, oak and red oak based on pre-smoothed data used during BDAT model building. These models now are the default models for these species; the original TapeR-models based one sectional data are now pushed to species code 37, 38 and 39, respectively. Updated all functions to handle the extended data set.
• corrected bug in function HDxoR()
• technical adjustments

TapeS 0.10.0

• added height tariff based on German NFI data to estimated tree height given diameter in breast height (DBH)

TapeS 0.9.0

• corrected bug in bdat_as_tprtrees(), when passing more than one tree from rBDAT::buildTree (class ‘datBDAT’)
• added 37th tree species based on an additional taper curve model, which is build on pre-smoothed beech data used during development of BDAT.
• corrected bug in plot function
• added function and indicator for residual variance to be set to zero to force taper curve through measurements; even more options possible
• added support diameter D001 (in 1% of height) at the stem base to avoid non-monotoneous taper curves for such trees (mainly very small trees of certain species). The support diameter is added based on the population average relation between D001 and D05.

TapeS 0.8.x

• corrected bug in tprDiameter, when bark=FALSE and interval != ‘none’
• corrected biomass estimation: tprBiomass now return aboveground biomass without component needles as the underlying functions do not include needles.

TapeS 0.8.5

• more flexibility in defining a tprTrees object
• corrected bug, when variable HdhG was not always available in tprAssortment
• corrected bug, when indexing was not correct deciduous trees in tprAssortment

TapeS 0.8.4

• simplified the return value of tprDiameterCpp (as in tprDiameter)
• added examples

TapeS 0.8.3

• allow for small diameter increase in taper curve when checking monotonicity (increase <= 1% of diameter)
• constraint in bark function: never return negative double bark thickness (c.f. e.g. Japanese larch) and diameter after bark deduction might not be smaller than zero

TapeS 0.8.2

• update examples in tprDiameter and tprDiameterCpp

TapeS 0.8.1

• updated helpfile of class parSort

TapeS 0.8.0

• plot method for class ‘tprTrees’
• call of ‘tprHeight’ in ‘tprAssortment’ corrected
• in subsetting: keep attribute about R0-status in object

TapeS 0.7.1

• updated helpfile for tprVolume

TapeS 0.7.0

• added confidence and prediction intervals into tprVolume
• added simTrees()
• some fixes in show and nfi_as_tprtrees coercion

TapeS 0.6.0

• renamed ‘trees’-class into ‘tprTrees’ to be more specific.
• renamed slot ‘H’ into ‘Ht’ (and accessort function)
• added cartesian product to function tprDiameter/Cpp, tprHeight and tprBark
• some updates to BDAT-coercion and show-method
• some updates to vignette

TapeS 0.5.1

• switched option TapeS_R0 from TRUE to FALSE (as default)

TapeS 0.5.0

• added accessor functions to objects of class ‘trees’
• added ‘show’ function

TapeS 0.4.0

• re-implemented component biomass estimation to get rid of dplyr/tidyr-dependency. Now component biomass is estimated using newly developed NSUR-biomass functions. Implemented using Rcpp.
• added coercion function to coerce nfi, sectional and bdat data

TapeS 0.3.0

• removed dependency on (unpublished) rBDATPRO-package, implementing biomass function via RCpp (instead call to rDBATPRO)
• added monotonicity check of taper curve right into class-constructor

TapeS 0.2.0

• included fitted TapeR models (data: SKPar) and updated corresponding data help file. Added this News file.

TapeS 0.1.0

• basic package development
